Safety Bob Sanders was an interested spectator during the Indianapolis Colts' three-day minicamp, which ended Sunday evening. He's still recovering from surgery on his left shoulder. Sanders insisted his rehabilitation is ahead of schedule but stopped short of declaring he'd be ready for the start of training camp in late July. The target date is Sept. 6, which is when the Colts open the regular season in the RCA Dome against New Orleans. "My No. 1 goal this year is to make sure I stay healthy and just focus on continuing to get better and not allow this past year to affect the way I play,'' Sanders said.
