THE season of Fremantle midfielder Paul Hasleby is over after just one pre-season game, with the Dockers confirming a knee injury suffered in the NAB Cup win over West Coast needed reconstructive surgery.

Hasleby's left knee buckled under pressure from Adam Selwood and Matt Spangher in the third quarter of Sunday's 44-point victory, leaving Hasleby in agony.

After being carried from the ground on a motorised stretcher, coach Mark Harvey initially said the 26 year-old had suffered medial ligament damage, meaning a spell of six to eight weeks on the sidelines.

However, after consulting with club doctors on Monday, scans also revealed anterior cruciate ligament damage which requires a reconstruction - ruling him out of the entire 2008 campaign.

"The left knee injury sustained in last night's game against West Coast will now require a full knee reconstruction," the club statement said.

"The scans revealed damage to the anterior cruciate ligament and Paul will undergo surgery as soon as this can be arranged."

While a massive blow for the club, it is also a personal calamity for Hasleby, who had been looking to reverse the indifferent form which saw him in danger of being traded at the end of last season.

Hasleby was forced to take a pay cut of around $150,000 a year to stay at the club, with protracted negotiations securing him a two-year extension to the end of 2009.

With a chance to become just the third Fremantle player to reach the 200-game milestone, Hasleby received life membership of the club last year following his 150th game.

Despite having an inconsistent season by his own standards, he collected 451 possessions at an average of 22.3 per game, second only to former captain Peter Bell.

And after an impressive pre-season consistently referred to by Harvey, it appeared the 2000 AFL Rising Star was on the verge of a big season.

He was included in the Fremantle travelling party which played against Carlton in South Africa and impressed in the first half against the Eagles before suffering the injury.
