Steelers pass rusher T.J. Watt has been cleared from concussion protocol and will be available to play against the Indianapolis Colts. Watt suffered a concussion during the Steelers' game against the New England Patriots and entered the protocol on Friday. He was a limited participant in practice on Tuesday before becoming a full participant on Wednesday. Watt took a hard hit on the first play of the game, but returned later wearing a visor with a darker tint. The NFL and NFL Players Association are conducting a review of the situation and Watt's placement in the protocol.
