Chicago Bulls guard Derrick Rose did not start Friday night's game against the Charlotte Bobcats due to a lower back strain and is not expected to play.

Bulls coach Tom Thibodeau said about an hour before tipoff that he'd make a game-time decision on Rose after the reigning MVP injured his back earlier in the week. Rose was not on the bench at the start of the game against the NBA-worst Bobcats.

C.J. Watson started in place of Rose, who is averaging 22.0 points.

Hornets' Jack to miss a week

The Hornets say starting point guard Jarrett Jack is expected to be out at least a week because of soreness in his left knee.

Jack had already missed three games because of the injury when he returned on Wednesday night in a loss to Chicago. Jack played nearly 28 minutes against the Bulls, scoring only four points to go with three assists, well below his averages of about 15 points and seven assists.

Jack's absence means the Hornets are without four of their top players for Friday night's game against Portland. The Hornets also are without shooting guard Eric Gordon (sore right knee), power forward Carl Landry (sprained left knee) and seven-foot forward Jason Smith (concussion).
