NFL.com's Gil Brandt reports that Temple defensive tackle Terrance Knighton had an impressive workout during his pro day.

The 6-foot-3, 317-pound lineman ran the 40-yard dash in 4.93 seconds and registered a 29-inch vertical leap, an improvement from his numbers at the NFL Scouting Combine where he ran the 40 in 5.21 seconds.

Cincinnati Bengals defensive line coach Jay Hayes, Cleveland Browns defensive line coach Bryan Cox as well as coaches from the Tampa Bay Buccaneers and the Denver Broncos were on hand.

Knighton also had a 8-9 broad jump and bench pressed 225 pounds 21 times, a disappointing figure.

Knighton tallied 54 tackles last season and 7 1/2 tackles for loss.
