Elton Brand made it clear before Thursday’s game against Denver that he has no intentions of shutting himself down for the season because of a sore right calf. Brand missed the Denver game because of the injury that has gotten worse over the last few days. He initially felt the discomfort last week against Indiana. “It’s been pretty obvious in the last two or three games he hasn’t been quite the same,” Mavericks coach Rick Carlisle said. “We’re going to sit him and try to get him right.” Brand couldn’t say whether he would be able to go Friday at Sacramento, but the Mavericks are going to aggressively treat the injury and try to get the 6-8 forward/center as close to 100 percent as possible before he returns. “It started in the Indiana game,” Brand said. “The first quarter, I felt something in there. It’s not progressing like we expected it to. It’s not getting better. “I’m in no way trying to shut it down [for the season]. I’m definitely trying to get back out there as soon as we can, so we’ll see. It’s like a game-to-game situation.” There are seven games left in the regular season, and the Mavericks remain long shots to get into the playoffs. In the last three games, Brand has not been himself, averaging just 2.3 points and four rebounds. He played only 12 minutes against the Los Angeles Lakers on Tuesday.
