ST. LOUIS (AP) — Kellen Clemens joked he might be getting more than the usual allotment of practice snaps this week.

The former backup quarterback got a lot more work Wednesday when the St. Louis Rams practiced for the first time since Sam Bradford's season-ending knee injury. Now it's the new backups, Brady Quinn and Austin Davis, who'll be getting limited reps while the Rams (3-4) prepare for their Monday night game against the Seahawks.

Two days after getting cut by the Jets, Quinn was signed in time for what the team referred to as a walkthrough.

"Obviously, there's a lot of things that are out of your control in life, not only in football, "Quinn said. "It's been a little bit crazy but that's kind of the world we live in, in the NFL."

Davis was among the final roster cuts before the opener, and stayed sharp throwing to high school wide receivers as a volunteer coach at Westminster Christian Academy in suburban St. Louis. The first few weeks, he said the kids didn't know who he was.

"Throwing the ball around with those guys and getting in their weight room and just staying ready, it's a difficult thing to do," Davis said. "But you have to do it."

For now they are emergency options behind Clemens, who'll be making his first start since 2011, and they're side by side in lockers, with offensive linemen on one side and linebackers on the other.

"We've got an extra day to prepare," Clemens said on Monday. "We'll be ready to rock and roll Monday night."

Quinn was a first-round pick by the Browns in 2007 and has bounced around. He didn't think picking up the system would be a chore, describing it as "like learning a different language, maybe Spanish and Portuguese where some things are similar and some aren't."

Since getting cut by the Rams, Davis spent one week with the Dolphins. He said he wasn't there long enough to confuse that playbook with the St. Louis system.

Davis was the third-stringer for St. Louis last year and did not play, and was on the Dolphins practice squad for one week earlier this fall.

Unlike Quinn, who had a workout before getting his deal, Davis said all he had to do was sign the paper work.

"It's been a tough six weeks, it feels like it's been two years," Davis said. "You just hit the ground running."

Bradford, who had started every game since the start of the 2012 season, was placed on injured reserve. He injured his knee in the fourth quarter Sunday in a loss at Carolina and is expected to undergo surgery in a few weeks when swelling subsides.

Offensive lineman Brandon Washington was released to clear roster space. Also, linebacker Jonathan Stewart was released from the practice squad.
