Safety Marcus Coleman was told to stay home and miss Sunday's game against the Ravens after missing a walkthrough on Saturday morning, the Houston Chronicle reported. "Marcus wasn't here because he was disciplined for not filling his team obligations," Capers told the paper after the 16-15 loss to the Ravens. It was the second time in three seasons that Coleman was forced to miss a game after violating team rules. In 2003, Coleman and outside linebacker Antwan Peek were ordered to miss the Buffalo game for violating team rules.
