ALAMEDA, Calif. Blaise Matuidi Jersey . - Oakland Raiders rookie quarterback Derek Carr returned to practice three days after being knocked out of a preseason game with a concussion and sore ribs. Carr practiced on a limited basis Monday and his status for the upcoming exhibition game in Green Bay on Friday night remains a question. Carr got hurt in the fourth quarter last Friday against Detroit when he was hit from behind by Larry Webster. Carr got up and immediately pointed at his ribs but later said the concussion was more of a concern. Carr has never had a concussion previously in his career. "I never had one ever so its a little scary to me," he said. "Obviously, Im feeling a lot better now than I was. Im just looking forward to taking it day by day. Obviously, its a slow process. Just progressing as the week goes on." Carr played well before the injury and even got one drive with the starting offensive line and receivers after starter Matt Schaub left the game. "It was exciting," he said. "I was screaming out plays. I was way too loud, they told me to calm down a little bit. It was great. It was good experience to be in with them. Its only the second game. I have a long way to get better." Carr lamented one throw in particular, when he overthrew Brian Leonhardt on a seam pattern on his first pass attempt of the game. Carr said he might have been too excited on that throw and his mechanics got out of whack. But Carr recovered to complete 9 of 16 passes for 109 yards and he threw a TD pass to Jake Murphy. Playing mostly against second-teamers, Carr fared better than Schaub did against the Lions first-string defence. Schaub has led the Raiders to one score in seven drives over the first two exhibition games as Oaklands first-team offence has struggled to find any consistency. Schaub has completed 11 of 20 passes for 108 yards, one interception and no touchdowns for a passer rating of 49.6. "How our offence goes is how the quarterback goes," Schaub said. "Just be more consistent in what were doing." Schaub has faced an unusual amount of blitzing for the preseason with defences bringing extra rushers on more than half of his dropbacks so far, according to Pro Football Focus. That has forced Schaub to get rid of the ball quickly, with only three of his passes — and none of his completions — going more than 10 yards downfield. Neither Schaub nor coach Dennis Allen is too concerned about the play of the first-team offence in the first two preseason games. But they expect a better performance in the dress rehearsal Friday against Green Bay. "Do I think we need to be able to go out and execute and make some plays? I think thats something that wed all like to see," Allen said. "A little bit more consistency would probably be the right term for what Im looking for offensively. Weve gone out and made some plays and done some nice things. We just havent been as consistent as we need to be and this would be a good week to get better at that."

Marie rink got back in the win column at the Olympic mens curling tournament with a 7-4 win over the host Russian squad on Wednesday.BOSTON -- The Red Sox demoted struggling switch-hitting outfielder Daniel Nava and recalled right-hander Alex Wilson on Wednesday. Nava, 31, was a big part of Bostons run to the 2013 World Series title, but was hitting just .149 with two homers and three RBI when he was optioned to Triple-A Pawtucket before the game against the New York Yankees. Wilson went 1-1 with a 4.88 ERA in 26 games with the Red Sox last year. Boston starters were hit hard recently and manager John Farrell went to his bullpen 10 times in the past three games, forcing him to add a reliever. "Given the number of innings by our bullpen the past four, five days, we needed to add another arm, some help out there," he said before Wednesdays game. "Also, we felt like we need to find a way to get Daniel Nava going again. His struggles at the plate, I think, are evident. Were trying to get him back to seeinng him be the player he has in the past. Steve Mandanda France Jersey. " Batting mostly from the left side of the plate in a platoon with Jonny Gomes in left field, Nava hit a career-best .303 for Boston last year with 12 homers and 66 RBIs. "Weve got to get a guy back that was pivotal to our success last year, particularly from the left side of the plate," Farrell said. "Its going to take some at-bats to do just that." Nava had been in the majors for a good portion of the past two seasons, so Farrell knew the news would be tough for the player. "As you might expect, he was disappointed," Farrell said. "I cant say there was disbelief. It was a disappointing message to deliver, given his role last year and the contributions. But in combination for the need for another reliever, while not liking it or deep-down agreeing with it, he knew it was a necessity." ' ' '
