Vancouver Whitecaps' striker Katie Thorlakson is unlikely to play Saturday's W-League home opener against the visiting Seattle Sounders Saints.
The 21-year-old from Langley suffered a potentially serious right knee injury during yesterday's practice at Burnaby Lake Sports Complex.
"It was an innocent little movement, and there was no collision or challenge," said Whitecaps' women's team head coach Bob Birarda.
Birarda said she changed directions and kept moving. A player nearby apparently heard Thorlakson's knee pop. After practice, she was helped off the grass field, grimacing and wearing a large ice pack around her knee.
Three of Thorlakson's eight goals last season were game winners. She led the club with eight assists.
Meanwhile, Newcastle United's third-string goalkeeper Tony Caig practiced for the first time with the Whitecaps' men's team yesterday. Head coach Bob Lilley will have to decide whether to start the newcomer or sophomore Josh Wicks when Minnesota Thunder visits Swangard Stadium on Sunday. Wicks allowed just one goal during two wins and a tie to start 2006.
