Middle Tennessee State guard Josh Walker recently conducted a workout for the Ravens, according to a league source.
Walker, an All-Conference USA selection who's drawing later-round draft grades despite not being invited to the NFL scouting combine, worked out for assistant offensive line coach Todd Washington.
Walker has official visits with the New Orleans Saints and Indianapolis Colts. The 6-foot-5, 323-pounder is known for his durability, never missing a game.
At his Pro Day, Walker ran the 40-yard dash in 5.22 and 5.25 seconds with a 27.5-inch vertical leap, a 7-9 broad jump, a 4.77 short shuttle and a 7.95 three-cone drill. He bench pressed 225 pounds 27 times.
