INDIANAPOLIS — Indianapolis Colts tight end Weslye Saunders has been suspended eight games without pay after violating the league’s policy on performance-enhancing substances.

League officials did not say Thursday what substance was found in Saunders’ test. He can practice with the Colts throughout training camp and will be eligible to play in preseason games. But he won’t be eligible to play in the regular season until after the Colts’ game Nov. 3 against Houston.
