Analysis:

Gibson was unable to take part in practice Wednesday and is reportedly still in pain while shooting, making it likely that he'll sit out his fifth consecutive game Thursday. The Bulls figure to roll with Bobby Portis as their starting power forward for the duration of Gibson's absence, which could very well last through the remainder of the season, especially if the Bulls -- who currently remain two games behind the Pistons for the final playoff spot in the Eastern Conference -- are eliminated from postseason contention.
