The Indianapolis Colts have addressed their offensive line and secondary concerns by signing veteran free agent tackle Gosder Cherilus, guard Donald Thomas and cornerback Greg Toler. The team also added linebackers Erik Walden and Lawrence Sidbury. Owner Jim Irsay confirmed the team has agreed to terms with all five players. Cherilus is a 6-7, 325-pounder who was taken with the 17th overall pick in the 2008 draft by the Lions. He has appeared in 75 games, 71 as a starter. Cherilus, 28, was a standout at Boston College. His arrival likely means Anthony Castonzo, the Colts’ 2011 first-round pick, will remain at left tackle with Cherilus stepping in on the right side. Thomas, formerly of the New England Patriots, is a 6-4, 305-pound guard who started seven games in 2012 and has also been with Detriot and Miami in a five-year career. Toler, 28, fills a void created by the departure of Jerraud Powers. Toler was a 2009 fourth-round pick of the Arizona Cardinals who has started 15 of 38 regular-season games. Walden made 46 tackles in 15 games last season, intercepting two passes. He has started 25 games the last two seasons. The 6-3, 265-pound Sidbury played defensive end for Atlanta, appearing in 48 games, all off the bench, over the past four seasons with 17 tackles.
