ANDERSON, Ind. - The Indianapolis Colts have put 2013 NFL sacks leader Robert Mathis and former starting guard Donald Thomas on the physically unable to perform list.
Both moves Sunday were expected, with Mathis and Thomas still recovering from season-ending injuries. Both can be activated any time before the regular season.
Mathis missed the first four games last season for violating the league policy on performance-enhancing substances, and the final 12 after tearing his left Achilles tendon in a private workout during the suspension.
Thomas missed all of last season after tearing his right quadriceps during training camp — the same injury that kept him out of all but two games in 2013.
Two other injured players, linebacker Nate Irving and running back Vick Ballard, were cleared to practice.
