Lynch played in five regular season games and both playoff games last season, primarily on special teams, after signing with Indianapolis on Nov. 27. He had six special teams tackles for the Colts. He made two tackles on defense and three more on special teams in the postseason. He also played three games with Tennessee before being released Nov. 22.
The move comes just two days after Indy put defensive lineman Fili Moala on season-ending injured reserve with a knee injury.
The Colts will hold a three-day mandatory mini-camp next week.
