Taj Gibson walked into the Bulls' locker room Tuesday night wearing a leg brace and a scowl. "I was pissed because I always want to be the guy who can go 82 games every year," Gibson said, when asked his reaction to spraining the MCL in his left knee. Gibson sat for the first time this season and just the sixth in his three-plus seasons in Chicago. Coach Tom Thibodeau confirmed a Tribune report that Gibson is expected to miss around two weeks. "Knowing me, I'm going to try to push it," Gibson said in his first comments since suffering the injury Sunday at Oklahoma City. "But I have to follow the doctors and follow my body. I never felt any pain like that before." Gibson said his left leg buckled and bent inward when he landed on Reggie Jackson's foot as Gibson descended from a blocked shot attempt. "I take good care of my body," he said. "It's just one of those things that happens, stepping on somebody else's foot. I really feel what Derrick (Rose) goes through and I have nowhere near anything what Derrick has." In fact, Rose and Gibson talked about left knee injuries as they sat getting treatment together. "He just said, 'What you're going through, imagine 100 times worse,'" Gibson said. Point, counterpoint: Thibodeau classified Rose's status as "just daily improvement." Nate Robinson termed it as "every day he gets better and stronger." Rose has said the decision on his return is up to him. - See more at: http://www.chicagotribune.com/sports/basketball/bulls/ct-spt-0227-bits-bulls-cavaliers-chicago--20130227,0,7922427.story#sthash.l5cDFPGZ.dpuf
