Darcy Lussick will be sitting out the start of the season after copping an ankle injury during a trial game against the Sharks on Saturday night.
Lussick, who captained the Sea Eagles in their loss, had to be helped from the field after injuring his left ankle in his first carry.
And Manly this morning confirmed that results of testing would have Lussick out for up to six weeks.
"Darcy Lussick will be sidelined for between four and six weeks," they said in a statement. "Results of scans revealed Lussick has a high ankle sprain but did not suffer a fracture.
"Lussick will not begin his rehabilitation program with the Manly medical staff."
The official statement came hot on the heels of a tweet from the prop which seemed to suggest that he would be out for the entire season.
"If anyone knows a kid who needs a pair of size 13 boots for up coming season let me know I'll send these to them," he wrote. "Worn once."
As the rumour mill went into overdrive, Lussick quickly clarified why he was actually handing over the boots.
"Haven't got rid of me that easy if I get injured I throw my boots away but though they could go to better use this time around," he added.
Manly coach Trent Barrett appeared concerned immediately after the team's 30-14 defeat, saying that he was disappointed for his player.
"We're still waiting to see how bad it is but it doesn't look particularly good at this stage, which is a shame for Darcy," Barrett said. "He's had a good pre-season and it was the first tackle of the game.
"We'll cross out fingers and hope he's all right. Trials are a necessary evil. I'm just disappointed for Darcy."
