It has been rumored that Terrell Suggs suffered a torn or partial Achilles tendon while playing basketball.
In reality, it doesn't matter.
If a player suffers any injury while doing anything away from the supervision of their NFL team, the condition is regarded as a "non-football injury."
As a result, the player's team could choose to not pay the player until the injury has healed.
