Matildas and Canberra United goalkeeper Lydia Williams has injured her left knee while playing for NSWL side Western New York Flash this morning Australian time.

The incident happened in the 13th minute of Flash's encounter with Matildas striker Lisa De Vanna's Washington Spirit.  It occurred when Williams went up to claim a corner and landed awkwardly on her left knee.

At 39.30 

Williams, who has become an integral part of the Flash's bid for the finals, was substituted out of the game immediately. The immediate fears are that the two time W-League Goalkeeper of the Year has torn her ACL for the second time.

If so, it could be a terrible blow for the Matildas with Williams a standout performer in Australia's silver medal winning run at the 2014 Asian Cup.

Western New York Flash have been contacted for news on the extent of the injury.

More news as it comes to hand.


Update

At 1.30pm, Canberra United CEO Heather Reid provided the first information that Williams injury is as serious as it appears. The scans are set to be on the same knee that Williams injured back 2012.
