Salvon Ahmed, a 25-year-old running back, has been signed to the Colts' practice squad after spending the majority of his NFL career with the Dolphins. He has played in 38 games over four seasons, totaling 867 yards and five touchdowns as a reserve. Most recently, he was with the Broncos during the offseason. With Jonathan Taylor and Trey Sermon injured, Ahmed may have the opportunity to contribute against his former team, the Dolphins, if needed.
