Crosby put the exclamation point on a 28-point second quarter as Walsh pulled away from Kentucky Wesleyan for its first win of the season.
Crosby flew in to block an Eman Westmoreland punt as teammate Daizon Earl scooped it up and returned 37 yards for a special teams score in the final seconds of the first half.
Crosby also made his presence felt on the field with a quarterback sack and a 71-yard fumble return to KWC’s 4-yard line that was punched in by Paris Salas for a Walsh TD on the ensuing play.
In five games played, Crosby has 23 tackles, including three for a loss.
