Washington Capitals center Nicklas Backstrom did not play for his native Sweden in Sunday's 3-0 loss to Canada in the gold medal game of the Sochi Olympics because he failed a doping test.

Swedish Olympic Committee spokesman Bjorn Folin said Backstrom tested positive for a substance found in an allergy medication that he has taken for seven years, according to The Associated Press.

The NHL released a statement Sunday about Backstrom's failed test, indicating that he will not face discipline by the league.

"We understand that Nicklas Backstrom tested positive for a substance banned 'in competition' by the International Olympic Committee," deputy commissioner Bill Daly said. "It is our further understanding that the positive test was the result of a common allergy medication taken by the player knowingly, with the approval of the team doctor and without the intention of gaining an illegal or improper performance-enhancing benefit. In addition, the specific substance that resulted in the positive test is not currently on the League's Prohibited Substances List.

"Subject to confirmation of the facts as we understand them, and given the fact that the substance is neither prohibited in the NHL nor was used in an improper manner here, we do not anticipate there being any consequences relative to Nicklas' eligibility to participate in games for the Washington Capitals."

Backstrom finished the Olympics tied for the team lead with four assists and tied for third in points while playing on Sweden's top line.

For the Capitals this season, Backstrom has 11 goals and 45 assists in 59 games.
