Kreutz felt the hamstring tighten up during the Bears' 22-19 win over the Buffalo Bills, but the center was able to finish the game.
"We feel like we're going to have our center," Bears head coach Lovie Smith said. "I'm almost sure we're going to have him.
"Olin is an iron man. Some guys seem to show up each Sunday, and you would definitely say that about Olin Kreutz. So I don't really see that being a problem."
The six-time Pro Bowl selection has played in 126 consecutive regular-season games. He's played in 183 total games, which is the seventh-highest total in Bears history. Kreutz hasn't missed a game since the 2002 season, when the center had midseason surgery to remove his appendix.
Other than Kreutz, the Bears had full participation at practice Thursday.
