The Colts placed their right of first refusal tender on Dulin on Wednesday, the Indianapolis Star reports.
Indianapolis will now be able to match any contract offer from another team, should Dulin receive any. Assuming the Colts retain Dulin, he'll be sticking around on a one-year, $2.4 million deal. He caught 13 passes for 173 yards and two touchdowns last season while also playing a significant role on special teams.
