DEERFIELD, Ill. -- Bulls general manager Gar Forman admitted on Thursday that he had already started kicking the tires on possible replacements to fill in for Joakim Noah, who will be out up to two months after hand surgery. Let's take a look at a few of the possibilities ...

Rasheed Wallace: He played for Bulls coach Tom Thibodeau in Boston and respects the coach. During the Bulls recent trip to Boston, Wallace interrupted his old coach's postgame press conference by saying, "I need a job." Thibodeau wasn't sure at the time if he was serious. He's going to find out quickly. Wallace would fit in well with the Bulls given that he already knows Thibodeau's schemes.

Chris Richard: The burly big man spent a portion of last season with the Bulls and was in training camp with the team earlier in the year before being waived. The Bulls know him, and he got along well with everyone in the locker room. He is playing in China.

Chris Johnson: The LSU product is playing for the Dakota Wizards in the D-League. The Wizards selected him in NBDL draft earlier this year and it paid off. He's averaging 19 points, nine rebounds and three blocks a game. He's also 6-foot-11. Will the Bulls be interested?

Joel Pryzbilla: The veteran center is in the final year of a contract which pays him almost $7.5 million this season with the Portland Trail Blazers. He's battled injuries, but he appears to be healthy again. The Blazers may be willing to talk, but what would the Bulls have to give up to get him? Is he even worth it?

Dan Gadzuric: Another veteran center who is in the final year of his deal, he has played sporadically for the Golden State Warriors all season. It shouldn't take much for the Bulls to pick him up if this is a direction they want to go.

Who do you think the team should go after? And don't say Brad Miller. He would be a great fit, but there is no way the Bulls want to pick up that contract. That's why they didn't sign him in the offseason.
