Rose did not require an MRI on the hamstring Tuesday, according to a source familiar with the situation.
The Bulls did not practice Tuesday and do not play again until Friday in Toronto against the Raptors.
Rose said Monday that he expects to play against the Raptors.
"It's just a minor sprain," Rose said. "Nothing serious. Hopefully I'll be better in a couple of days, but it's nothing big at all."
Bulls executive vice president John Paxson said Rose was feeling better Tuesday but reaffirmed that the 25 year-old was day to day after injuring his hamstring. Rose did not have to undergo an MRI Tuesday, but the organization wants to see how the hamstring responds after an off day on Tuesday.
Rose injured the hamstring on a drive to the rim, converting a layup with just less than four minutes to play. He doesn't remember exactly when the injury occurred but was removed from the game by coach Tom Thibodeau and replaced by Kirk Hinrich. Rose went toward the end of the bench and was checked by assistant trainer Jeff Tanaka.
"I really don't know," Rose said of when exactly the injury occurred. "I remember coming down the court. Really didn't feel it until after I came down and went back to the bench and [the training staff] was asking me about it. Then coming back in, it was a play where somebody knocked the ball out of bounds or something like that, and they said I wasn't moving good enough to be out on the court so they came and subbed me out."
Rose missed the past year and a half while recovering from reconstructive left knee surgery.
