CLEVELAND — Chicago Bulls star guard Derrick Rose may miss his third straight game with a toe injury.

Rose did not participate in the team's morning shootaround. Coach Tom Thibodeau said it will be a game-time decision whether the league's MVP plays Friday night against the Cleveland Cavaliers. Rose has been sidelined with a sprained left big toe he first injured Jan. 10.

The Bulls will likely take a cautious approach with Rose, who is averaging 20.8 points and 8.7 assists. Rose hasn't played since last weekend against Toronto.

Even without their top player, the Bulls blew out Phoenix 118-97 on Tuesday. C.J. Watson started for Rose and scored 23 points.

The Bulls have the league's best record at 13-3 and host Charlotte on Saturday.
