Former Iowa State defensive lineman David Irving is visiting the Kansas City Chiefs, Oakland Raiders and Seattle Seahawks, according to a league source.
Irving, dismissed from Iowa State last year, worked out for the Chicago Bears, Chiefs, New England Patriots, New York Giants, Raiders and Seahawks.
The 6-foot-7, 273-pounder ran the 40-yard dash in 4.84 seconds with a 38-inch vertical leap and a 10-8 broad jump with a 4.53 short shuttle and a 7.27 three-cone drill.
Irving was suspended in 2013 after being charged with domestic assault against the mother of his child with the charges subsequently dropped two months later.
