Bears' brass called the Robinson cut their toughest call.
"That probably was our toughest decision," said Chicago GM Jerry Angelo. "It really came down to a matter of what we're doing with our scheme and Bryan did have value in our scheme. We had him at the end position (and) the defensive tackle position, but in the end we felt that there were some younger players going into their second and third years and we felt that the arrow's going up on them and felt good about them."
Robinson was the Bears' longest-tenured defensive player. He tallied 331 tackles and 16.5 sacks during his six seasons in Chicago.
Released wide receivers David Kircus and Reggie Swinton, linebackers Michael Young and Andrew Battle, running back Avon Coubourne and fullback Stepehn Trejo; placed strong safety Brian Walker on injured reserve. Walker, the team's starting free safety the past two season, had arthroscopic surgery on his left knee Friday and will miss the entire season.
"We felt -- and the doctors felt -- that (Walker's) period of recovery would be shorter than the (entire) season...but we just needed to move on," Lions head coach Mariucci said.
The Lions made the bulk of their cuts Saturday, releasing a dozen players including veteran long-snapper Bradford Banta and physical, second-year cornerback Roderick Babers.
The Vikings trimmed their roster to 53 without any big surprises. Players cut Sunday included WR Ryan Hoag, WR Ben Nelso, WR Lane Danielsen, S Derek Ross, RB Butchie Wallace, S Oliver Celestin, CB Horace Willis, CB Jermaine Mays, TE Brody Liddiard, DE NIck Rogers, C Bill Conaty and G Anthony Herrera.
The Vikings were able to get to the NFL-mandated 53-man roster limit without sacrificing any of their eight 2004 draft picks.
