ST. LOUIS – Falcons defensive end John Abraham, who has a history of groin problems, was declared inactive against the Rams with a groin injury on Sunday.
Abraham leads the Falcons in sacks with eight.
Abraham had groin problems earlier in his career, but had started 55 of the last 56 games for the Falcons, including all 16 games in 2007 and 2008. He started 15 of 16 games last season.
Lawrence Sidbury, who has been inactive for four of the last five games, was announced as the starter for Abraham.
Abraham recorded two sacks against Baltimore to give him eight this season, second most among defensive ends in the league. The New York Giants’ Osi Umenyiora went into this week’s game leading all ends with nine sacks.
Before missing the St. Louis game, the upgrade in his performance was dramatic. Abraham had only 5 1/2 sacks last season after registering a franchise record 16 1/2 sacks in 2008.
Abraham was named second-team All-Pro in 2008, but was a bit miffed that he didn’t make the Pro Bowl NFC team.
Other players declared inactive for the game against the Rams included cornerback Dominique Franks, running back Gartrell Johnson, linebacker Spencer Adkins, tackle Garrett Reynolds, guard Mike Johnson and defensive tackle Trey Lewis.
