Kubiak said he did not know whether the hamstring was strained or torn.
"We're still in the evaluation process," Kubiak said, per the Houston Chronicle. "We're going to get a couple of different opinions over the next couple of days. Obviously, it's a big concern going forward. We have to do what's best for Andre. He's going to miss some time. Right now, I don't know if that's three or four days or a few weeks."
