Colts special teams coordinator Brian Mason suffered torn knee ligaments in a sideline collision during the final play of Thursday night's preseason game against the New England Patriots. The injury occurred when Mason was struck by players engaged in a block near the out-of-bounds line after a Hail Mary pass.

Mason, who joined the Colts in 2013, was evaluated upon returning to Indianapolis. His availability is uncertain and will depend on the final diagnosis and potential need for surgery.

The injury could impact the Colts' special teams operations, as Mason oversees all aspects and needs mobility to manage players from across the roster. He is in his fourth season with Indianapolis and is aided by senior assistant Joe Hastings. The Indianapolis Star first reported the injury.
