The Indianapolis Colts bolstered their front lines on Thursday, agreeing to terms with tackle Gosder Cherilus and three other players.

Cherilus spent his first five NFL seasons with Detroit, which selected him in the first round of the 2008 draft out of Boston College. He started in 71 of his 75 career appearances.

In addition, the club brought in defensive back Greg Toler, linebacker Erik Walden and guard Donald Thomas.

Toler compiled 128 tackles, five interceptions for 168 yards and two scores, with one sack in 38 games over three seasons for the Arizona Cardinals.

Walden is coming off a 46-tackle, three-sack, two-interception season for the Green Bay Packers. Heading into his sixth pro season, the Middle Tennessee State product brings 153 tackles, eight sacks and a pair of picks in 68 games to the Indy defense.

Thomas, a sixth-round pick of the Dolphins in 2008, has started in 21 of 43 games with Miami, Detroit and New England in five NFL campaigns.
