Mike Nolan and Jack Del Rio are ready to suit up. The 49ers' coach and his Jaguars counterpart have the NFL's permission to wear dress suits designed by Reebok during two games this season. Nolan is expected to debut his old-school outfit, black suit, a white shirt and a red-and-gold-striped tie, at the 49ers' home game against Seattle on Sunday. Del Rio also will wear a suit-and-tie ensemble in Monday night's home game against the Giants.
