Geelong star Gary Ablett has injured his right hamstring as West Coast came from 15 points down in the final quarter to post a 15-point win in their AFL clash at Optus Stadium.
The Cats trailed by 32 points at halftime on Sunday night but booted six goals to nil in the third quarter to turn the contest on its head.
Cats duo Cameron Guthrie (ankle) and Nakia Cockatoo (knee) had already gone off injured by that stage.
And when Ablett pinged his right hamstring while running for the ball early in the last quarter, Geelong were down to one fit man on the bench.
The Cats led by seven points at that stage and extended that to 15 points at the 16-minute mark of the final term.
But West Coast went on a goal spree from that point on, booting six goals in a golden 10-minute stretch to snatch the 14.11 (95) to 11.14 (80) win in front of 54,535 fans.
The win improved West Coast’s record to 2-1 before Saturday’s home clash with Gold Coast.
Geelong are 1-2 and have plenty of problems on the injury front, with Ablett the biggest of the lot.
The former Sun, who was hampered by a hamstring injury during the pre-season, was visibly disappointed as he hobbled off down the players’ race after the latest setback.
West Coast will be sweating on the fitness of goalsneak Liam Davis, who injured his right leg while soccering through his third goal late in the fourth quarter.
Geelong were lucky to be only 16 points down at quarter-time after losing the inside-50m count 24-10.
Alarm bells were ringing when they entered halftime with a 32-point deficit.
But Patrick Dangerfield and Tom Hawkins inspired a remarkable fightback in the third term to put their side in the box seat.
Lachie Fogarty missed three crucial shots on goal in the final term, with West Coast launching a remarkable fightback to secure victory.
