The Indianapolis Colts will be without running back Ahmad Bradshaw and safety John Boyett for the start of training camp. Bradshaw, a free-agent acquisition in June, has been placed on the physically unable to perform list while he continues to recover from January surgery on his right foot. Boyett, a sixth-round draft pick, was placed on the non-football injury list as he continues his rehabilitation from surgery on both of his knees while he was a senior at Oregon. Both players count against the Colts’ 90-player training camp roster and can be activated whenever they gain medical clearance. Boyett’s placement on the NFI list is due to his medical situation occurring before he joined the team. The Colts report to Anderson University Saturday for the start of camp. Bradshaw offered an up-beat tweet shortly after the Colts announced the roster moves. “For all y’all believers, just know tht I will b ready to rock. Come regular season. So, thank u, and keep believing. God-bless!’’ he wrote. The team signed Bradshaw to a one-year contract that could be worth as much as $2 million, expecting him to upgrade its running game. He had his right foot in a protective boot as he watched the mandatory minicamp in June and coach Chuck Pagano made it clear the team would err on the side of caution as Bradshaw recovered from the foot surgery.
