The Dolphins cut Foster (undisclosed) with an injury designation Tuesday, Tom Pelissero of NFL Network reports.
Foster faced steep competition for a depth role in Miami's crowded receiving room, and he's dealing with an undisclosed injury to boot. Since racking up an impressive 27 catches for 541 yards and three scores as an undrafted rookie in Buffalo back in 2018, Foster hasn't logged much in the way of meaningful regular-season production.
