Marshall left offensive tackle Garrett Scott had a private workout for the San Diego Chargers this week, according to a league source.
He has previously visited the Oakland Raiders, Kansas City Chiefs, Miami Dolphins and the Tampa Bay Buccaneers.
Scott is regarded as a middle to late-round draft target as a versatile offensive lineman who can also line up at guard, having started at left guard in the past.
The 6-foot-5, 310-pounder ran the 40-yard dash in 5.08 seconds at his campus Pro Day workout.
He bench pressed 225 poudns 25 times and had a 9-7 broad jump. He has 34 1/2 inch arms.
He was a three-year starter.
