Since returning from a dislocated right elbow in Week 7, Tucker has been overmatched. He hadn't played in the team's previous 33 games because of a combination of three different injuries.
Tucker is also playing right guard, which has slightly different footwork involved from the left side.
Edwards started all 16 games a year ago at left guard and has started once there this season as well as getting a start on the right side.
The team decided they had enough depth at guard to waive Mike Gandy last week after he started five games at right guard this season and a total of 30 games at three different positions over the past three years.
Craig Krenzel has been sacked 15 times in three starts with a majority of that pressure coming from the interior of the line.
At times Tucker's ineffective play has seemed to impact C Olin Kreutz, who is the captain of the line. The three-time Pro Bowl center has been called for false starts in trying to get off the snap quickly and help Tucker with his blocks.
With time Tucker should return to form, which made him a Pro Bowl alternate in 2001, but at this time it might be better to go with a healthy Edwards.
The Chicago Bears made three moves to fill their practice squad Tuesday. The team signed wide receiver Kareem Kelly and linebacker Jerry Schumacher to the squad and waived wide receiver Jimmy Fryzel.
Kelly is a 6-0, 186 pound first-year player who spent time with New Orleans and Baltimore during his NFL career. The all-time leading receiver at USC caught one pass for 12 yards and returned three kickoffs for 47 yards during the 2004 preseason with Baltimore.
Schumacher has been in training camp with the Bears each of the last two seasons and was allocated to NFL Europe by Chicago for the 2004 NFLEL season.
Initially waived by the Bears this year during training camp, Fryzel was signed to the practice squad for Week Ten.
