Nathan Dyer could be out of action for Swansea for two months with an ankle injury, having only recently signed a four-year deal at the club.
The 28-year-old returned to Swansea in the summer having spent last season on loan at Leicester City, where he picked up a Premier League winners medal after his 12 appearances - all as a substitute - for the champions.
Swansea confirmed Dyer, who has been at the club since 2009 and said his new deal would keep him at the club until the end of his career, will undergo surgery on Monday to remove extra bone growth in his ankle.
"I am bitterly disappointed," Dyer told the club's official website. "I was feeling good after completing pre-season training and being involved in the friendlies and the first three games of the campaign.
"I started to feel some pain in my ankle after returning from the training camp in America. I saw a specialist last week and the MRI scan revealed the extra bone growth at the back of my ankle.
"There is not a lot I can do about it, but I am determined to work even harder after my operation to play my part for the team on my return."
Dyer's only league appearance this season came in the 2-0 home defeat to Hull City on August 20.
