Wednesday's signing of defensive end Turk McBride will not make up for the loss of Israel Idonije if the Bears fail to re-sign their own unrestricted free-agent defensive end.
But the former Saint does give the Bears some veteran depth behind starters Julius Peppers and Corey Wootton and last year's first-round draft pick Shea McClellin.
The 6-foot-2, 278-pound McBride, 27, was a second-round draft pick (54th overall) and has played in 66 games and started 24 in six NFL seasons with Kansas City (2007-08), Detroit (2009-10) and New Orleans (2011-12).
He has 9½ career sacks, 6 forced fumbles, 3 fumble recoveries and 119 tackles but has never come close to living up to his draft-pick status.
The Bears, according to the Charlotte Observer, also have made a one-year offer to Carolina Panthers cornerback Captain Munnerlyn, 24, a potential nickel back if unrestricted free agent Kelvin Hayden isn't re-signed.
