Add Robbie Dixon's name to the list of Alpine Canada's injured skiers.

A concussion will keep Dixon out of this weekend's World Cup race in Wengen, Switzerland. The Whistler, B.C., resident is returning to Canada for more tests.

"Still have some lingering symptoms from the fall in Bormio," Dixon said in a Twitter post. "Wengen's a no go."

Erik Guay will also miss the Wengen race with a sore back.

Alpine skiers already gone for the season with injuries are Francois Bourque (knee), Louis-Pierre Helie (concussion, knee) and Kelly McBroom (broken ankle).

Veteran Kelly VanderBeek also won't return this year after undergoing a second surgery on the knee she ripped up in December 2009.

Dixon suffered the concussion in a fall in a Dec. 29 downhill race at Bormio, Italy. It's not known when he can return to racing.

"It's time to get him back to Canada for further investigation," Dr. Stephen French, a member of Alpine Canada's medical staff, said in a release.

Dixon's best result this season is an eighth in a super-giant slalom race at Beaver Creek, Colo.
