Here is one report.
Sounds real good if he is healthy.
Justin Harrell, Tennessee (6-4 3/8, 300, 5.06)
Harrell had a complete workout at the Combine. He ran his two 40s in 5.04 and 5.07 and also recorded a 30½-inch vertical jump, 9-foot long jump, 4.79 short shuttle, 7.63 three-cone drill and 24 bench presses. He worked out again on March 21 at Tennessee's Pro Day when his weight was 314 pounds and he posted 31 bench presses. Harrell played tight end and defensive end in high school, where he was a three-year starter. He also played basketball, averaging 17 points a game as a senior. Harrell redshirted at Tennessee in 2002 and played the final eight games of 2003 after breaking his ankle before the season. He tore his bicep in September 2006 and tried to play with one arm. He would have been a three-year starter if not for injuries that forced him to miss starts. Harrell is a very athletic player who can be a difference-maker if healthy. He has long arms with good strength and can play nose tackle. He needs to learn to rush the passer better, but is a very solid player if healthy.
