The Chicago Bulls, trailing 2-1 in the opening round of the 2012 NBA Playoffs, are currently unsure who will start at center against the Philadelphia 76ers on Sunday's pivotal Game 4.

According to Bulls head coach Tom Thibodeau, the team may start either C Omer Asik or PF Taj Gibson in the absence of C Joakim Noah, with C Brian Scalabrine providing the depth off the bench:

"Omer (Asik) obviously can handle that position," Thibodeau said. "Taj (Gibson) has played both (center and power forward). It gives you versatility there. We feel like we'll be OK. We have three bigs. We also have Scal. We feel we have more than enough."

The Bulls and 76ers will begin play at 12:00 p.m. CDT.
