One of the defending Western Lacrosse Association champion Langley Thunder's key players has been slapped with a two-year ban.

The Canadian Centre for Ethics in Sport (CCES) announced Wednesday that Lewis Ratcliff has received a two-year sanction for an anti-doping rule violation.

Ratcliff's urine sample, collected during in-competition doping control on Sept. 12, 2012, revealed the presence of oxandrolone and clenbuterol, two prohibited anabolic agents, as well as oxycodone, a prohibited narcotic, a CCES press release stated.

"In response to the CCES' notification of the adverse analytical finding, Mr. Ratcliff waived his right to hearing, acknowledged the anti-doping rule violation, and accepted a two-year sanction ending November 9, 2014," the press release states.

"The athlete, who resides in Redmond, Washington, is ineligible to participate in any capacity with any sport signatory to the Canadian Anti-Doping Program (CADP), including training with teammates."

During the 2012 WLA season, the left-handed Ratcliff finished tied with Athan Iannucci with 57 points each, tops among Langley's Western Lacrosse Association team's scorers.

Ratcliff also led the Thunder in goals with 30, helping Langley finish at the top the WLA regular season standings with a 12-6 record.

He was far and away the top WLA scorer in the playoffs, tallying 23 goals and 49 points in just 10 games in leading the Thunder to their second consecutive WLA title, as well as their second Mann Cup appearance in as many years.

Ratcliff and the Thunder lost to the Ontario champion Peterborough Lakers in six games, in the Mann Cup championship best-of-seven national championship series.

The drug testing took place during the Mann Cup in Peterborough.

The Thunder acquired Ratcliff from the Nanaimo Timbermen last April, in exchange for Langley's first and second round picks in the 2014 WLA draft.
