The Texans returned from New England Sunday night with a few less starters.

Right tackle Seantrel Henderson, cornerback Kevin Johnson were hurt in the loss to the Patriots, and now the Texans must figure out ways to replace them.

On Monday, head coach Bill O'Brien said Henderson's year is over because of a "significant ankle injury", while Johnson would "definitely miss a lot of time" because of a concussion.

Henderson, who joined the team in free agency in March, was replaced by starting left tackle Julién Davenport. Rookie Martinas Rankin took over Davenport. Losing Henderson is "tough", according to O'Brien, who explained how the Texans will try to replace him on the roster.

"We have practice squad guys, Kendall Lamm on the 53, we have practice squad guys to replace that on the 53, and then we'll also probably work some guys out and see what's going on with that," O'Brien said. "So, I think we're in the process of kind of deciding what to do with all that."

Rankin was in on 63 offensive snaps, with Henderson exiting after his 11th snap of the afternoon. A third round selection from Mississippi State in this year's Draft, he's capable of playing all along the offensive line.

"I'm pretty sure we'll both be getting some opportunities at both sides, so we'll see how it goes," Rankin said.

Because of Johnson's injury, the Texans will now consider a number of corresponding moves, one of which might involve shifting Kareem Jackson from safety back to cornerback. But such a move would be tough for the Texans to make, because of how well Jackson played safety on Sunday.

"There's a lot of possibilities as we move through the next 48 hours because we have tomorrow to be able to look at some guys, maybe, but that's a possibility and that's why it's good to have a guy like Kareem," O'Brien said. "The issue there is that Kareem played well at safety. To move him over to corner, that's not the easiest decision to make because he played a heck of a game at safety yesterday."

After taking Tuesday off, the Texans will practice Wednesday through Friday at the Houston Methodist Training Center. They'll face the Titans in Nashville on Sunday.
