BYU seniors McKay Jacobson, Jameson Frazier, Corby Eason, J.J. Di Luigi and Terence Brown (in that order) run the 40-yard dash for NFL scouts at BYU's Pro Day on Thursday, March 29.

Scouts did not release the timed results. Just posted this video to give viewers a peak at what Pro Day is like; Matt Putnam, Matt Reynolds and Travis Uale also ran the 40 for scouts on Thursday.
