Anthony Adams remains upbeat

LAKE FOREST, Ill. -- Chicago Bears defensive tackle Anthony Adams refused to speculate on the reasons for his failure to dress against the Philadelphia Eagles, the first time the nine-year veteran was inactive for a contest since 2008, which snapped a streak of 47 games played (including playoffs).

"I don't know if it was a numbers game, or what it was, or what it wasn't, I don't know," Adams said on Wednesday. "All I know is I didn't play."

It was a quick reversal of fortune for Adams who started the previous two weeks at nose tackle as Matt Toeaina sat out due to a knee injury. But with Toeaina ready to return last Monday night, coupled with the increased role of rookie second-round selection Stephen Paea, Adams found himself as the odd man out.

So far this season the Bears have kept only four defensive tackles active on game day.

"I knew going in, I just didn't want to make a big deal out of it," Adams said

The Bears rewarded Adams with a new two-year deal after the steady defensive lineman started all 16 regular season and both postseason games in 2010. However, the nose tackle was sidelined with a calf injury for most of training camp and subsequently opened the year as a reserve. Adams did start Week 6 and Week 7 in place of Toeaina.

This isn't exactly unchartered territory for the Penn State product. After he signed with the Bears as a free agent prior to the 2007 season, Adams was a healthy scratch on a few occasions his first two years in Chicago.

"I've been there before," Adams said. "You can either show panic or show poise. I choose poise. I'm going to come out of this thing just like I did the last couple of times and do my job."
