The Dolphins quickly found a potential running back replacement for Alexander Mattison on Monday just hours after it was reported that Mattison would miss the 2025 season. Miami is signing Aaron Shampklin on a deal, NFL Network's Mike Garafolo reported.
Shampklin hasn't seen much action on the NFL field since he was picked up by the Cowboys in 2022 after going undrafted out of Harvard. He spent that season on the Colts' practice squad. He had a short run in the USFL in 2023.
