The hard-luck player, released in March by the Bears because of past injuries, grabbed the back of his leg after going down during the workout on Tuesday. The incident was seen on Instagram Live, with Cohen falling to the floor after backpedaling.
Cohen played three full seasons with Chicago but made it to only three games in 2021 before tearing knee ligaments. He missed the rest of that season and then was released by the Bears.
A fourth-round draft pick in 2017, Cohen had a strong rookie year as a running back and kick returner. He made All-Pro as a punt returner in 2018, when he led the NFL with 33 run-backs for 411 yards.
