Bulls guard Alex Caruso is dealing with a foot injury that forced him to sit out a game against the Hawks. Coach Billy Donovan believes it's a day-to-day setback and not too serious. The Bulls already have key players out due to injuries and need their bench players to step up, especially on defense. Torrey Craig filled in for Caruso in the starting lineup. Jevon Carter, who signed a three-year deal last summer, hasn't had the expected impact and has seen his minutes decrease.
