Adams' role for Falcons uncertain

LAKE FOREST, Ill. -- The fact Chicago Bears defensive tackle Anthony Adams was able to practice Thursday without restrictions is a good indicator the veteran will be active against the Atlanta Falcons. But the amount of reps he will get is unclear.

Adams sat out most of the preseason with a lingering calf injury that occurred in the early portion of training camp.

"You can never dictate how many plays you are going to get or when you are going to be needed," Adams said after practice on Thursday. "You never know what to expect when you are heading into a game. I really don't know.

"I guess I won't know (how my calf will respond) until the first couple of plays when I get a lot of pressure on me and guys are trying to cut me."

Matt Toeaina started in place of Adams at nose tackle during the preseason, and could receive the bulk of the playing time Sunday if the Bears choose to ease Adams back into the mix. The Bears are high on Toeaina, who started 10 games in 2010 and signed a contract extension prior to the end of the season.

"(Our depth at defensive tackle) is endless," Adams said. "You can move guys around, first string, second string, we won't miss a beat whoever is in the game. It's going to be a fun thing to be a part of."
