Robinson (hamstring) officially didn't practice Wednesday, Tori McElhaney of the Falcons' official site reports.
Robinson now hasn't practiced since last Wednesday, when he was limited, due to a hamstring injury. He likely will need to mix into drills Thursday and/or Friday to have a chance to play Sunday at Tampa Bay. If Robinson is inhibited or sidelined again this weekend, Khalil Herbert will serve as Atlanta's No. 2 RB behind top option Bijan Robinson.
