INDIANAPOLIS (AP) — Colts safety LaRon Landry has been suspended four games without pay for violating the NFL's performance-enhancing substance policy.

Landry has started all four games for the Colts (2-2) and had 18 tackles.

He cannot return to the team until after Indy's Oct. 26 game against Pittsburgh.

The news came Monday on the same day reigning NFL sacks champ Robert Mathis was reinstated and then placed on the reserve/non-football injury list. Mathis also was suspended for violating the performance-enhancing substance policy. He will miss the rest of the season after tearing his Achilles tendon during private workouts in Atlanta.
