Wilson signed with the Colts on Tuesday.
Wilson bounced in and out of the starting lineup in Detroit over the past four seasons, with his stint highlighted by last year's career-high 98 tackles. The 30-year-old could serve as the No. 3 safety in Indianapolis, where Malik Hooker and Khari Willis are expected to be the starters. The team also has rookie third-round pick Julian Blackmon, but he's still rehabbing from an ACL tear he suffered in December.
