(SportsNetwork.com) - The Miami Heat embark on a four-game road trip, starting Sunday afternoon against the Boston Celtics at TD Garden. This was once one of the best rivalries in the NBA, but times change. For the Celtics, Doc Rivers was traded to coach the Los Angeles Clippers, Kevin Garnett and Paul Pierce were shipped to the Brooklyn Nets and Ray Allen is apparently still deciding whether or not to play this season. For the Heat, the four-time reigning Eastern Conference champions, a fellow named LeBron James bolted South Beach for his hometown Cleveland Cavaliers. And, for the time being, Dwyane Wade is sidelined with a right hamstring injury. Both teams are under .500 and both teams are in the midst of two-game losing streaks. The Heat begin this trek Super Bowl Sunday and will stop in Detroit, Minnesota and San Antonio. They dropped both games on a short homestand, first to the Milwaukee Bucks, then to the Dallas Mavericks. On Friday, the Heat turned a double-digit lead into a 93-72 loss to Dallas. The Mavericks held the Heat to just three points over a nearly 14-minute span in the third and fourth quarters. Dallas went on a 39-3 run during that time to end a seven-game, regular-season losing streak to the Heat. Miamis stale finish -- which came after Dallas started the game ice-cold from the field -- tempered what was a career night for Hassan Whiteside, who set a franchise record with 14 rebounds in the first quarter. The 7-foot center ended with 16 points and a career-high 24 rebounds for the Heat. James Ennis added 15 points off the bench, All-Star Chris Bosh scored 12 and Mario Chalmers had 10 in Miamis fourth loss in six games. We anticipated that this probably wouldnt be a game where wed win by outscoring them, wed have to keep this game down, said Heat coach Erik Spoelstra. Second half, they dominated and played their style. The Celtics came back from a 3-3 road trip with a home loss to the Houston Rockets, 93-87, on Friday. Boston dropped the last game on the sojourn to the Minnesota Timberwolves for its two-game slide. Against the Rockets, Brandon Bass and Marcus Thornton each scored 17 points for the Celtics. Tayshaun Prince chipped in 13 off the bench and Avery Bradley managed 10. Boston has lost three of its last four. Bass capped a 9-2 run with a pair of free throws to help the Celtics, who were down as many as 19 earlier in the game, close to within three just past the midway point of the fourth. Donatas Motiejunas did damage for the Rockets, converting crucial buckets to keep the Rockets ahead. The Celtics had numerous opportunities to get closer in the final minutes, however, Josh Smiths free throws put the Rockets up seven with 51.6 seconds to play. Thorntons layup preceded an offensive foul by James Harden that trimmed the Boston deficit to 90-87 with 27 seconds left. Corey Brewer converted a pair of free throws before Bradleys missed 3-pointer sealed it for the visitors. I thought we played with much more urgency, said Celtics coach Brad Stevens of the second half. The Heat won the first game between the two teams this season back in December and have won five of the last eight regular-season matchups. Boston is 11-1 in its last 12 regular-season games versus the Heat as the host. Wholesale Patriots Jerseys .5 million contract with the right-handed reliever.

Sources tell TSN Hockey Insider Pierre LeBrun the international tournament will likely return in September 2016 rather than 2015.LOS ANGELES - As DeMar DeRozan, the Raptors long-time iron man, lay sprawled out on the baseline, his leg twitching in obvious pain, each one of his concerned teammates stood around him holding their collective breath. Exceeding all expectations to begin the season, this tight-knit group has become known for their solidarity, both on and off the floor. Now, with their leading scorer sidelined indefinitely, theyll need it more than ever. After exiting Fridays loss to Dallas early in the second half with a groin injury, the Raptors announced that DeRozan sustained a torn left adductor longus tendon, keeping him out of the lineup for the foreseeable future. DeRozan was driving to his right, nearly four minutes into the third quarter, when he slipped and fell to the floor. With the assistance of a trainer, he was eventually helped up and to the locker room, where he remained for the duration of the contest, one the Raptors would eventually lose after a late-game rally fell short. There is no immediate timetable for his return to basketball activities, according to the team, and his status will be updated over the coming weeks. The Raptors All-Star guard is averaging a team-high 19.4 and 4.2 rebounds over the clubs first 16 games. As the focal point of their improved attack, DeRozan accounts for just under 29 per cent of the Raptors offensive possessions when hes been on the court, the highest usage rate of any player on the team. Having to replace his production, for however long he is out will be a challenge, though its not necessarily a fatal blow given their depth and balance on both ends of the floor. More than anything else, it will be an adjustment. The sixth-year guard was logging roughly 34 minutes a night to lead the team after ranking third in the NBA in playing time last year. He has missed just 11 games to this point in his career (the Raptors are 8-3 in those contests). Weve got to [continue to] play, said Kyle Lowry, who will be relied upon even more without his backcourt running mate. Next man up. Its a team, not about one guy. If anybody goes down, the next man has to step up. The Raptors are the leagues sixth-ranked team in bench points, thanks in large part to the addition of Lou Williams - leading the East in scoring among reserves - the versatile James Johnson and Greivis Vasquez, wwho has rediscovered his jump shot this past week.dddddddddddd I think weve got one of the best, and I say this in a humble way, benches in the league, Vasquez said. Somebody else is going to step up. Lou will step in or myself or James or whatever coach wants to do. Now hes got a squad. Hes got a team. And now he needs to, and he will, put it together. Somebody went down and we almost won. That wasnt good enough. I think we have guys that can step up and do their job. All three wing players figure to see expanded roles in DeRozans absence, with one of them likely stepping into the starting lineup. Although Williams, the reigning Eastern Conference Player of the Week, seems to be a natural fit to fill the scoring void - averaging 14.3 points, third on the team - Dwane Casey may prefer to utilize his instant offence off the bench. The same can be said of Vasquez, the back-up point guard, leaving Johnson, who could start at the three-spot and push Terrence Ross to the two, giving them more size and defensive acumen up front. Landry Fields could also be in the mix for spot minutes. Well decide that in the next day or so, Casey told reporters after practice on Saturday, declining to name a replacement ahead of Sundays meeting with the Lakers. We dont know now, well talk about that later. One thing is for certain, the 13-3 Raptors will face their biggest and most telling early-season challenge. Lowry, who will be in consideration for Eastern Conference Player of the Month next week, will become more important than ever, handling increased responsibility in the teams half-court sets. Jonas Valanciunas could also be in line for a bigger piece of the offensive pie in the low post. One thing about our team, we have guys that can step up and they are definitely going to have to because thats a big scoring load in DeMar, echoed Amir Johnson. We have guys that can come in and step up for us. DeRozan accompanied the team to Los Angeles, his hometown, Saturday afternoon, where they will begin a three-game road trip without his services on the court. Generally, the recovery time for a groin injury of this nature can range from weeks to months depending on the severity. Until they learn more about DeRozans status and can get him back in uniform, their celebrated team unity will be put to the ultimate test. ' ' '
