Tony Pauline, from TFY Draft and Sports Illustrated, reports via Twitter that former Baylor WR Josh Gordon pulled/hurt his quad during his 40-yard dash. He continued with the workout and reportedly did not drop a pass.

Our View: The injured quad would help explain the slower than expected 4.5 40-yard dash. Even with the injury it sounds like Gordon put on an impressive show at his pro day.
