Derrick Rose still has back spasms

CHARLOTTE -- Chicago Bulls guard Derrick Rose did not play against the Charlotte Bobcats in his team's 95-64 blowout win on Friday.

The team considered him a game-time decision because of ongoing back issues. Rose's status for Sunday's game in Boston also is on a day-to-day basis.

"[He's] still the same," Bulls coach Tom Thibodeau said Friday night. "Day to day. More precautionary. Just wanted to give him another day of rest. And we'll see where he is [Saturday]."

Rose, who has been dealing with back spasms for several weeks, was taken out of Monday night's game against the New Jersey Nets in the second quarter because of tightness in the back.

"[It feels] the same," Rose said before Friday morning's shootaround. "A little tight. But I should be able to deal with it."

He played just 22 minutes in a 90-67 victory Wednesday against the New Orleans Hornets.

Rose has been getting massages and other treatments to relieve some of the pain.

C.J. Watson started in Rose's place, scoring seven points on 3-of-7 shooting.

"I knew he wasn't going to play today," Watson said. "I knew that [Thursday] coming in. Because we have a big game against Boston. I already knew."
