Barrow midfielder Robin Hulbert says he may have played his last game for the club, with a cruciate ligament injury likely to have ended his season.
The 31-year-old signed a one-year extension to his contract at Holker Street in May, but has been reduced to just eight appearances this campaign.
"Unfortunately I think I might have played my last game for Barrow," Hulbert told BBC Radio Cumbria.
"I feel I have let the managers and supporters down with the injury."
Hulbert's time at Barrow has been hampered by injury, with groin and hamstring injuries limiting him to just 20 outings last term.
However the damage to his knee is a blow to the Plymouth-born player, who is one short of 260 league appearances in his 15-year professional career.
"It's the biggest challenge I am going to have to meet," Hulbert added.
"Obviously it's going to be a long-term injury, and will probably take me up to the end of the season.
"I don't want to put an end to my career like that, I want to keep playing.
"I believe I am going to come back from it and play part-time football if I have to."
The former Port Vale player joined Barrow following his release by Darlington in June 2009 and has made 65 league appearances for the club.
Hulbert was also part of the club's FA Trophy winning side in 2009-10, although he was dismissed in the final against Stevenage.
