DeMar DeRozan has suffered a torn left adductor longus tendon, the Toronto Raptors announced on Saturday.

DeRozan does not have a timetable for return to basketball activity.

Tests revealed the injury on Saturday after DeRozan suffered it on Friday.

The Dallas Mavericks' brass heaped praise on Dwane Casey before the two teams squared off on Friday in Toronto.

Mark Cuban recommended that the Raptors hire Casey shortly after the 2011 NBA Finals run. Casey was an assistant coach on the Mavs' title team.

“I was very complimentary of him to them because of the attention he pays to detail, his understanding of the game, his ability to relate to players, he’s the total package,” Cuban said.

“I think he didn’t get a fair shake where he was as a head coach prior (in Minnesota). I mean, he was the difference-maker for us. We don’t win a championship without him.”

“There were a lot more established coaches that he passed on,” Rick Carlisle added.

“He really targeted Dwane as a guy that he knew could take a group of younger guys, mould them and instill a defensive philosophy and a defensive disposition in how they played. The very first year the record wasn’t great but the defensive numbers did a 180. From there they have built it up each year. Dwane has earned the right to have a team this good and he has done a great job of building it up to this point.”

Lou Williams and DeMarcus Cousins have been named NBA Eastern and Western Conference Players of the Week, respectively, for games played Monday, Nov. 17, through Sunday, Nov. 23.

Williams helped the Toronto Raptors to a 3-0 week, finishing fourth in the Eastern Conference with 23.7 ppg and ninth with 2.0 spg.

Cousins led the Sacramento Kings to a 2-1 week and paced the league in rebounding (16.3). He averaged 25.7 points (second in the league) on .577 shooting (30-for-52) and tallied five blocks.

The Toronto Raptors recognized Vince Carter during a first quarter timeout of Wednesday's game against the Memphis Grizzlies.

Carter requested a trade from the Raptors in 2004 and has largely been booed in his return visits ever since.

“Amazing,” Carter said. “It’s just an amazing feeling to see it, to relive it, to see all the people react as each play was happening. It was an honest reaction. It was in the moment, the feel of the moment.”

“I think when we were all growing up we all got to witness what he was doing here in Toronto,” Quincy Pondexter said. “He was Air Canada. He was the man. A big piece of him is still in the city and he loves it. I knew there was something (special) about it from the time we got on the plane. I usually sit next to him and he was really focused on this day. It means a lot to him.”

James Johnson is out indefinitely with a severe right ankle sprain.

Johnson has averaged 7.6 points, 3.8 rebounds in 19.4 minutes per game this season.

Johnson suffered the injury in Saturday's game.

James Johnson had his most impactful game for the Toronto Raptors in their 104-100 win over the Orlando Magic.

Johnson played strong on-ball and off-ball defense and had 10 rebounds in just 21 minutes.

“Everyone knows he’s a little crazy,” Greivis Vasquez said of Johnson. “Personally I love his craziness. Ten rebounds in (21) minutes? That’s energy. You can’t teach that.”

Vasquez also compared Johnson to Tony Allen, who was a teammate of both players with the Memphis Grizzlies.

“You need someone crazy in your locker room,” Vasquez said. “Someone who is not afraid to fight for you or anything like that. He would die for the whole team.”

The Toronto Raptors lead the NBA in efficiency differential with a +12.6 mark, while the Houston Rockets and Golden State Warriors are second and third at +11.6 and +10.2.

The Raptors rank second in offense (113.7 points per 100 possessions) and are sixth in defense (101.4 points per 100 possessions allowed).

Kyle Lowry has become one of the NBA's best point guards and also one of the best players in the game who hasn't made an All-Star Game.

"At the end of the day, I can't worry about what other people do," said Lowry. "I have to go out there and do my job. If people make all-stars, and I'm winning, I'm happy with that. I'm not caring about anything but winning."

Lowry has matured and become more of a leader during his time with the Toronto Raptors.

"He's gotten away from the reputation of being a bad teammate or whatever the perception was," Dwane Casey said. "So he's grown from that."

The Toronto Raptors had 42-22 run leading to the playoffs last season and they hope the continuity of keeping their roster will allow them to start the new season fast.

"We hope it does," Dwane Casey said. "I think it does help us. Continuity with terminology, continuity with schemes, continuity with play calls, continuity with the familiarity with each other. They know some things are non-negotiable offensively, some things are non-negotiable defensively. That helps. Anytime you can keep teams together."

Amir Johnson said prior to sitting out Sunday's game that "the best thing we have is chemistry, because we have players who have been together for a couple of years now."

"It goes a long way, honestly," DeMar DeRozan added. "Everybody knows everybody's game. Everybody knows where they like the ball. It's just second nature now. Sometimes chemistry can beat talent. A lot of nights. I think we have that chemistry. We've been through a lot of struggles.

"Especially last year, with a lot of us learning on the go, from playing in the playoffs. It was just a lot that we took from it, that we've grown from. And the work that we put in this summer on top of the motivation we had from all last season, it definitely gives us the hunger to want more."
