Central Florida linebacker Shaquem Griffin ran a time of 4.38 seconds in the 40-yard dash Sunday at the NFL scouting combine in Indianapolis, the fastest time for a linebacker since 2006.
Griffin's twin brother, Shaquill, a cornerback with the Seattle Seahawks, also ran a 4.38 at last year's combine.
Shaquem Griffin's 4.38 came in his first attempy at the 40-yard dash. He ran a 4.58 in his second attempt.
Griffin had his left hand amputated at age 4 because of amniotic band syndrome, a congenital condition. He was a late addition to the list of combine invitees, getting his formal invitation on Jan.
