Eduard Gutknecht went the distance with George Groves despite suffering a bad cut in the 10th round

Germany's Eduard Gutknecht remains in a coma 12 days after his defeat by George Groves, the British fighter says.

Gutknecht, who needed surgery after the fight, is in a "stable condition", says the British Boxing Board of Control.

The 34-year-old fell ill in his changing room following his defeat on 18 November, and was taken to hospital.

Groves, who beat Gutknecht to retain his WBA International super-middleweight title, has set up external-link a fund to help the boxer and his family.

"He is still in hospital in a coma after having surgery the night of our fight 12 days ago," wrote Groves on Twitter.

Groves scored a unanimous points win in the fight at Wembley's SSE Arena.
