It’s early to panic, for sure. But that Mario Williams is compelled to get a second opinion on the hip issue that’s been holding him out of practice is certain a cause for concern.

John McClain and Mark Berman are both reporting that Williams is not with the team Monday as he seeks a second medical opinion.

Hopefully it’s again judged to be not serious. But a lingering issue for Williams from the start is certainly a bad thing for the Texans.

The possibility of him missing some action would be less of a big deal if the team adds Aaron Schobel, but indications seem to be it could be a while before the former Bills defensive end decides where to sign and strikes a deal.

UPDATE, 11:55: @NickScurfield of houstontexans.com tweeted this from Gary Kubiak on Williams: "All the reports are good. We expect him to get back here and get back on the field here shortly."
