GLENDALE, Ariz. -- It was bad enough for Arizona quarterback Kevin Kolb that Oakland's Tommy Kelly sacked him in the end zone for a safety.
What the Raiders defensive end had to say about Kolb after Oakland's 31-27 loss to the Cardinals Friday night probably hurt much worse.
"He is skittish. He is scared back there," Kelly said. "Anytime anybody gets close to him he starts looking at the refs. As a defensive lineman you love a quarterback like that. He ain't even trying to look at the routes no more. He is paying attention to us and you ain't going to get nothing done like that."
Kolb is fighting John Skelton for the starting quarterback job, and his night was a mix of good and bad.
Skelton, meanwhile, made the most of a brief opportunity. He took just five snaps, but that was enough for him to throw the first touchdown pass for either quarterback candidate this preseason.
Oakland running back Mike Goodson, who fumbled the ball away twice, left later in the second quarter with a chest injury. Arizona starting left tackle Levi Brown was sidelined in the second quarter with a triceps injury. Raiders wide receiver Jacoby Ford also left early with a foot injury.
Skelton's 3-yard toss to a wide open Anthony Sherman was part of Arizona's 17-point second quarter.
Coach Ken Whisenhunt wasn't prepared to make any quarterback pronouncement.
"Not with only five plays for John," Whisenhunt said. "I think I'll have to get John some extended time this next week."
Skelton entered the game after Oakland fumbled the ball away at its 23. He completed 3 of 3 passes for 23 yards.
Whisenhunt said he didn't want the starting offensive line to play in the second half and he didn't want Skelton playing behind the backups.
Skelton said he understood, grudgingly.
"There's a little frustration but at the same time you kind of understand it," he said. "They want to give everyone an equal opportunity but at the same time you can't have the o-line in there for an extended period of time just to make everything equal. I kind of was a little mad about the decision but at the same time I understand it."
Kolb was 3 of 3 for 22 yards in Arizona's opening touchdown drive but was sacked by Kelly in the end zone on the Cardinals' next possession. He completed 3 of 6 passes and was sacked three times.
Raiders backup quarterback and former Cardinals starter Matt Leinart left the game in the third quarter with a cut on the index finger on his right (non-throwing) hand after he took a late hit from Arizona's Ricky Lumpkin, who was called for a personal foul on the play.
"We're going to get X-rays and see what happened, but we'll see what happens," Leinart said.
The Cardinals lost starting left tackle Levi Brown to a triceps injury in the second quarter. Whisenhunt said he would know more about the severity of Brown's injury on Saturday.
In a matchup of teams tied at No. 23 in the AP Pro32, Oakland had a 184-52 advantage in yards at halftime but trailed 24-11, thanks to two turnovers that resulted in 10 Arizona points. Another Cardinals TD came on a blocked punt as Arizona won for the first time in three preseason games.
"We have got to execute better. We've got to eliminate the turnovers," Oakland coach Dennis Allen said. "The self-inflicted wounds , they are hard to come back from so we have to execute in that regard a lot better."
Arizona's Justin Bethel, a sixth-round draft pick out of Presbyterian College (enrollment 1,200), blocked the punt and returned it 19 yards for a touchdown. He later blocked an extra point.
Carson Palmer played the first half for Oakland, completing 13 of 24 passes for 107 yards. He was intercepted once.
Darren McFadden ran nine times for 34 yards for the Raiders (0-2), who scored their first touchdown of the preseason when Lonyae Miller ran in from the 1-yard line against the Arizona reserves in the third quarter.
Rookie Eddy Carmona kicked a 52-yard field goal for Oakland after Sebastian Janikowski booted three field goals and called it a night.
The Cardinals' Ryan Williams, the second-year pro playing for the first time since tearing his right patella tendon in the preseason a year ago, rushed five times for 25 yards, including a 3-yard touchdown run.
"I can't even lie, I was so nervous," Williams said. "I felt like I was six years old again playing Pop Warner."
