"I don’t know, but he didn’t feel good so I just said ‘Get out,’" Kubiak said. "He went 35, 40 minutes (in practice) and looked great, so I’m hoping he’ll be right back out here. We’ll see."Foster is coming off a remarkable sophomore season. As a rookie, Foster had a mere 54 rushing attempts, but emerged out of nowhere last year to lead the league in rushing yards (1616), rushing touchdowns (16) and yards from scrimmage (2,220). Two of Houston's other star players on offense -- tight end Owen Daniels (flu) and Andre Johnson (dislocated finger) -- also sat out on Friday. I don't think any Texans fans mind if the emphasis is on Wade Phillips and what he's doing to improve the defense during camp, but hopefully Foster's hammy is just fine over the weekend, and that Matt Schaub has his full aresenal of playermakers to get back to work with sooner rather than later.
