In a season that has been a blessing in terms of dealing with injuries, Monday’s game with the Heat may go down as the one that finally got the Raptors. Kyle Lowry, the one player the Raptors cannot do without, left the game in the third quarter with a sore left knee. Lowry and LeBron James collided midway through the second, leaving Lowry in a heap clutching the affected knee. The two went knee to knee, with Lowry clearly getting the worst of it. As he is wont to do, Lowry eventually got back up and played through the pain. But with three minutes and 12 seconds to go in the third, the Raptors made the decision to shut down the limping Lowry for the rest of the night. “He bumped knees and it puffed up a little bit,” Raptors head coach Dwane Casey said after the game. “He couldn’t go. The X-rays were negative so we’ll just have to wait and see how he is tomorrow.” Lowry did not talk to the media after the game. He was taken to the team bus from the dressing room on a cart but even walking from the cart to the bus through the mandatory TSA screening appeared to be a chore. He was accompanied by the teams’ director of sports science Alex McKechnie who oversees all training, rehab and strength and conditioning for the Raptors. Casey was already being cautious with both Lowry and DeMar DeRozan who have logged big minutes for him all season and was trying to get them extra rest whenever the opportunity presented itself. Casey was asked how cautious he would be now in light of Monday’s events. “His body will tell us, he will tell us and the medical people will tell us if he can go,” Casey said. “We are not in the position to just totally shut him down. I think we have to be smart with it. We’ll see where it is. Greivis (Vasquez) is playing well for us right now but if (Lowry) can go we’re going to have to find him some time. We’ve been trying to cut his minutes down and this may get him a little bit more (attention that way) but I don’t think we can totally shut him down.” Lowry’s teammates have seen Lowry play through plenty this season and were optimistic this time would be no different. “Kyle, he’s a tough guy,” Raps forward Terrence Ross said. “He always comes through. No matter what he’s going to find a way to get back on the court.” DeRozan echoed those comments.
