Quarterback Mark Gronowski is back with the Dolphins.
Gronowski signed with Miami after going undrafted this year, but was waived a little over a week ago. The Dolphins announced that he has re-signed with the team on Sunday and that they have also signed linebacker Cam Riley.
Gronowski played four seasons at South Dakota State before transferring to Iowa last year. He started 67 games during his college career.
Riley was undrafted out of Florida State last year. He spent time with the Patriots and the Titans, but did not see any regular season action.
The Dolphins placed offensive lineman Jamaree Salyer on injured reserve and waived cornerback Ethan Robinson with an injury designation.
