Carolina placed Cohen (hamstring) on its practice squad injured list Monday, Darin Gantt of the Panthers' official site reports.
The transaction means Cohen won't be eligible to be promoted to the active roster for at least the next four games. If he is eventually going to log his first regular-season action since Week 3 of the 2020 campaign, the earliest he'll have a chance to do so will be in Week 14 against the Saints.
