Report: NT Chapman to visit Raiders

Alabama NT Josh Chapman is scheduled to visit the Raiders, as well as the Titans and Falcons, Scout.com reported. If coach Dennis Allen switches from a 4-3 to a 3-4 base defense, he'll need to acquire talent to man NT. The roster's only NT is Travis Ivey, who was signed to the practice squad late last season. Chapman underwent knee surgery in January to repair a torn ACL.
