In most cases, the activation of a player from the physically unable to perform list means the player is (wait for it) physically able to perform.
In the case of Colts running back Ahmad Bradshaw, it means something else.
Per a league source, the Monday move of Bradshaw to the active roster occurred because the Colts allowed Bradshaw to practice eight days ago.
Specifically, he took some handoffs during a walk-through practice. The Colts called downplayed it as “mental reps.”
The league investigated the situation, determined otherwise, and required the Colts to move Bradshaw to the active roster.
While not a major issue or a significant disciplinary measure, it removes any misunderstanding from the rules. If a player on the PUP list participates in practice, he’ll be activated, whether the team is ready to activate him or not.
