The Texans worked out free agent kickers Billy Cundiff, Olindo Mare and John Potter on Tuesday. It always creates a stir when teams try out big-name kickers, but the Houston Chronicle's John McClain reports the Texans are "happy with Shayne Graham." The Texans are just updating their emergency list. Graham has converted 15-of-17 field-goal attempts this season, and owns a stellar 86.1 career percentage.
