Timberwolves guard Jimmy Butler's sore back kept him out of most of practice Sunday and could keep him out of Monday's game against Portland at Target Center.
"He didn't do much today," Wolves coach Tom Thibodeau said after Sunday's short practice. "Just getting treatment. We'll see how he is [Monday]."
Citing back spasms, the Wolves listed Butler as questionable for Monday's game.
Butler's back appeared to tighten up in the second half of Saturday's loss to Phoenix. Butler briefly left the court, getting some treatment in the locker room, before returning to the bench.
Still, he played. He re-entered the game early in the fourth quarter, playing the final 10:05. But even when he was in the game, he appeared to be laboring.
"I could tell his back was bothering him," Wolves forward Taj Gibson said after the game. "He was in a lot of pain. Every time he was trying to move, every time he was trying to cut he was in a lot of pain. He tried to thug it out, being the warrior that he is."
With the Wolves down five with 4:08 left, Butler's steal and end-to-end basket spurred a 6-0 run that put the Wolves up a point with 1:22 left. But, after Isaiah Canaan's three free throws with 6.1 seconds left, Butler had two chances to score. He missed a driving layup with 1.7 seconds left. Then, off an inbounds play, Butler missed a 16-footer with 0.3 seconds left.
Thibodeau said he hadn't decided who would start in place of Butler should the back keep him out of action. When Butler missed two games because of illness early in the season Thibodeau inserted Shabazz Muhammad into the starting lineup. But Muhammad has not been a part of Thibodeau's rotation of late; he hasn't appeared in the past seven games.
