According to the Texans, Foster was injured on the first play of team drills at Methodist Training Center. He was taken across the street to Reliant Stadium on a golf cart with ice on his leg.
Head Coach Gary Kubiak said he didn't know much more than that, but Andre Johnson told us it's not time to worry just yet.
"That's just the nature of this business," said Johnson. "Sometimes it happens. You just have to find a way to recover from it and come back stronger. I know how hard Arian works so I'm pretty sure he'll be fine. I don't think it's anything major or anything like that. Like I said, if it was anything real serious where he would have to miss a lot of time, we would have known by now."
This is the first day that Gary Kubiak didn't like a lot of what his team showed on the practice field. Tuesday's workout lagged at times for the Texans. And for the first time, rookies and first-year players wrestled with an expanded playbook.
"I think I gave them too much time off. We had too long a weekend," said Kubiak. "Now, we've got to get going again today. Some young guys are going backwards today. Obviously, we're getting into a lot more stuff this week so the challenge gets bigger."
