German Eduard Gutknecht remains in hospital almost two weeks after losing to George Groves, the British boxer confirmed.

Gutknecht, 34, collapsed in his dressing room after his defeat to Groves at Wembley on November 18, and needed eye surgery.

Groves, whose triumphed allowed him to retain his WBA International super-middleweight title, set up a fundraising appeal to help the boxer and his family.

Groves said in a statement on Wednesday: “Out of respect for Eduard and his family’s privacy I haven’t tweeted anything about his medical situation so far. However, he is still in hospital in a coma after having surgery the night of our fight.”

Gutknecht’s injury is the second to occur at the same venue in eight months. In March, Nick Blackwell collapsed after being beaten by Chris Eubank Jnr. He suffered bleeding on his brain and was placed in an induced coma.
