One of the best underdog stories of the Sochi Olympics may be nearly undone. Whitney Mercilus Jersey . According to The Globe and Mails James Mirtle, the Latvian mens Olympic team - which finished eighth in the hockey tournament - now faces possible disqualification after a second player has allegedly tested positive for a banned substance. Mirtle cites a report from Latvian web site sportacentrs.com that states an unnamed player has turned up the teams second positive drug test of the tournament. Forward Vitalijs Pavlovs failed a drug test following Latvias 2-1 quarter-final defeat to Canada. Under Olympic rules, hockey teams do not face disqualification until multiple players test positive for banned substances. The eighth-place finish improved Latvia to 10th in the IIHF world rankings, which is a key determinant to Olympic qualification. The top nine teams in the IIHF world rankings received automatic berths to the Sochi Games, which was the reason why Norway (ranked ninth through 2012) was able to avoid the qualification tournaments that saw Slovenia, Austria and Latvia qualify by beating the likes of Germany, France and Belarus. IIHF rankings are based on tournament performance over a four-year span, including both the Olympic hockey tournament and the World Championships. Shane Lechler Jersey .

This place is awesome. This place is great when youre wearing the silver and black and its a great place to play as an opponent.

We havent won a game. How much worse can it get than that, than not winning a game?While the Raiders are the NFLs only winless team and in the midst of their worst stretch in more than a half-century, the first-place Cardinals are playing some of their best football in years.Palmer and a stiff defence are the big reasons. Despite throwing Arizonas first interception of the season, Palmer has mostly avoided the big mistakes that often doomed him during his year and a half in Oakland.He also has shown the ability to make the key throw, with his two biggest being a 33-yard touchdown pass to Michael Floyd in the second quarter and a 22-yarder to John Brown on third-and-8 late in the fourth. That set up Chandler Catanzaros 41-yard field goal that sealed the win with 29 seconds to go.Ellington, who was slowed by a rib injury, had 24 carries for 88 yards and caught six passes for 72 more yards to take pressure off Palmer.Theres always a lot of energy and pent-up emotion when you come back and play against somebody, coach Bruce Arians said.

Carr went 16 for 28 for 173 yards.The Raiders fell behind 14-0 early, but cut it to 14-13 midway through the third period when Sebastian Janikowski hit a 53-yard field goal with new holder Matt Schaub. The Raiders made the switch after Janikowski struggled with punter Marquette King and then missed a 53-yard field goal last week.Ellington then keyed a big drive for Arizona, running for 40 yards, catching a 16-yard pass and drawing a 20-yard pass interference penalty on Miles Burris. Taylor replaced him and scored on a 4-yard run.The Raiders were unable to cross midfield on their final three drives and lost again.Palmer arrived in Oakland with much fanfare after the Raiders dealt a first- and second-round pick to Cincinnati midway through the 2011 season. But Palmer was not able to turn the Raiders into a playoff team, falling one game short his first season, and was traded following the 2012 season.Palmer got off to a fast start, throwing the two first-half touchdowns, including Floyds leaping grab over Tarell Brown. The Cardinals picked Oakland apart on third downs, converting 9 of 14 chances.Its like one of those things where you dont know what the problem is, defensive tackle Antonio Smith said. Each week youre going in trying to fix something and each week you wonder why its not working.But Carr got the Raiders back into it with a 55-yard deep strike to Butler that set up McFaddens 1-yard score.
