No Indianapolis Colts comebacks at Houston this time, just a humbling trip home after a 34-24 season-opening loss to the Texans Sunday at Reliant Stadium. Arian Foster scored his second and third TDs in a career day during the final quarter as the upstart division rival Texans wore down the defending AFC South champions. It’s just the second time in 17 divisional meetings the Texans have defeated the Colts. The other was 27-24 at Houston in 2006. Foster, a second-year pro, ran for a career-best 231 yards on 33 carries. The Texans slammed through a Colts defense missing injured safety Bob Sanders. The oft-injured 2007 NFL Defensive Player of the Year exited late in the first quarter with an elbow injury. He was listed as questionable to return and did not. http://www.indystar.com/article/20100912/SPORTS03/100912005/1004/SPORTS/Colts-fall-to-Texans-34-24
