In 2015, Clay was not able to make the 53 man roster and was placed on the Bucs practice squad. Later on, he was picked up by the Lions which did not work out and he landed on the Ravens roster. Clay found himself placed on the injured reserve prior to August of last year and was released.
The Carolina Panthers saw an opportunity this past week and signed him to a one-year contract, possibly due to his effective return skills. While with the Ravens he returned the football for 587 yards and a touchdown on 37 total return attempts.
