Quarterback AJ McCarron would have seen his first action for the Oakland Raiders on Sunday -- if the Seattle Seahawks hadn't kept the ball for the final 8:25 of their 27-3 victory at Wembley Stadium in London.

Oakland's final possession of the game ended with consecutive sacks of Derek Carr, and as the Raiders kicked a field goal for their only points of the game, the quarterback entered the sideline medical tent to have his left shoulder examined.

When Carr emerged, Oakland coach Jon Gruden had decided not to send him back into the game when the Raiders got the football again because there was "too much fire around the quarterback."

"I wanted to go back in, and Coach said, 'Absolutely not,'" Carr said during his postgame press conference. "After he saw that, he just wouldn't let me. And I begged him for a solid five minutes.

"It happened last year in New England. I think it was in Mexico. I hurt my ankle or something. We're getting beat, and it's like, 'Man, I want to finish with my team.' That's the worst -- not being able to finish with your team, I think. Losses happen, bad things happen, but not being able to finish a game with your team, especially when you're losing, man, that'll rip your heart out. No matter how I feel, I wanted to finish. But Coach, he wanted to protect me. That's all."

That put McCarron on his deck for his first action for Oakland since the Raiders obtained him in a trade with the Buffalo Bills on Sept. 1.

But Oakland never got the ball again. The Seahawks ate up the rest of the clock by converting three consecutive third-down snaps and getting another first down on the first play after the two-minute warning to allow Seattle quarterback Russell Wilson to kneel out the game.

The Seahawks sacked Carr six times, including one by former Alabama standout Jarran Reed, a defensive tackle for Seattle.

"I made the decision if we did get the ball back, we go to McCarron," Gruden said. "There's too much fire today, too much fire around the quarterback. ...

"We didn't get an opportunity to step up in the pocket and go through progressions. It was closing in quick. You know, Derek was on the run a lot, and he got hit too much. We can't allow that to happen. We just can't do it."

Oakland's offensive line played with two rookies at the tackle spots -- first-round pick Kolton Miller at left tackle and undrafted Brandon Parker filling in for injured Donald Penn at right tackle.

The Raiders also lost left guard Jon Feliciano to a rib injury during the game. Feliciano started in place of injured regular Kelechi Osemele, and his departure put Justin Murray on the field for his first NFL action.

"We didn't play well enough," Raiders center and former B.C. Rain standout Rodney Hudson said. "That's what happens when we don't play well enough."

Oakland also had two wide receivers exit the game to enter the NFL concussion protocol. Former Alabama standout Amari Cooper and ex-West Alabama standout Seth Roberts left after hits to the head, and neither returned.

Carr described his shoulder as "bruised," and he doesn't expect to miss any playing time, particularly since the Raiders are entering their bye week and don't play again until Oct. 28, when they play the Indianapolis Colts.

Oakland and Indianapolis have 1-5 records. The Colts play the Bills on Sunday before visiting Oakland.

The Raiders sent a fifth-round pick to Buffalo to make McCarron their backup quarterback.

During the offseason, Buffalo traded its quarterback of the previous three seasons, Tyrod Taylor, to the Cleveland Browns, then signed McCarron as a free agent and used the seventh pick in the 2018 NFL Draft on Wyoming quarterback Josh Allen, bringing in two players to compete with their 2017 backup, Nathan Peterman, for the starting job this season.

After McCarron was traded, Peterman started the first two games before being replaced by Allen.

A fifth-round draft choice from Alabama in 2014, McCarron played in 12 games with four starts during four seasons with the Cincinnati Bengals, who had Andy Dalton entrenched as their quarterback.

After McCarron earned All-State honors in football and baseball at St. Paul's in Mobile and helped the Saints win the AHSAA Class 5A football championship in 2007, he was the starting quarterback for the Alabama teams that won the BCS national championships for the 2011 and 2012 seasons. With the Crimson Tide, McCarron became the school's all-time passing leader, won the Maxwell Award and the Johnny Unitas Golden Arm Award and finished second in the Heisman Trophy balloting for the 2013 season.
