HOUSTON (AP) – Texans quarterback David Carr will miss at least one game and perhaps more with a sprained right shoulder, meaning veteran Tony Banks will get his second start of the season Sunday against New England.

Carr was injured late in the first quarter of Sunday’s 12-10 victory at Buffalo when Bills linebacker Jeff Posey came free for a sack, driving Carr’s throwing shoulder into the turf. Center Todd Washington prevented a touchdown by sweeping the ball out of bounds for a safety.

“An MRI revealed David has a sprain of the AC joint,” coach Dom Capers said Monday, referring to the point where the shoulder meets the collarbone. “We’re going to have to determine what progress he makes in his rehab from that point on.”

It’s the second time this year that Carr, who took every snap as a rookie last season, has been knocked out of a game in the first quarter. He limped away from a sack at Indianapolis on Oct. 26 with a sprained right ankle and missed one game, which Banks started and won over Carolina.

At that time coaches did not sign another quarterback because they were confident Carr would rebound quickly. This time, the Texans reacted to Monday’s MRI test results by immediately signing Mike Quinn to the practice squad.

“We just felt that with David not being able to throw the football and Mike’s been with us and knows the system we have … it was in our best interest now to bring Mike in,” Capers said of Quinn, who spent last season as the emergency No. 3 quarterback but never was active for a game.

The opening on the practice squad came when linebacker Shantee Orr was promoted to the 53-man roster. Fellow linebacker Jimmy McClain was cut Monday to make room for Orr. However, Quinn is not eligible for games on the practice squad, meaning the Texans will go into Sunday with only Banks and rookie Dave Ragone active. The emergency third-stringer will be receiver Jabar Gaffney, who played quarterback in high school.

Capers said the Texans, who at 4-6 have matched last season’s victory total, will not rush Carr.

“We’re going to do what’s best for David Carr,” Capers said.

Carr and most other players were not available Monday. The exception was cornerback Marcus Coleman, who along with injured linebacker Antwan Peek were suspended without pay for the Bills game because of unspecified team violations.

Peek was out anyway with a dislocated toe on his left foot, but Coleman had started each of the previous 25 games in the franchise’s history.

“I do want to apologize to my teammates … and secondly I want to apologize to my family and my friends and the fans,” Coleman said. “Whatever internal matter happened, I’m ready to put it behind me and just go back to work and be ready to play on Sunday.”

Capers said the two were fully reinstated Monday, although Peek will miss Wednesday’s practice as he continues to heal. Defensive linemen Corey Sears (left ankle) and Gary Walker (right foot) also will be held out of workouts.
