British welterweight Jerome Wilson is in hospital after suffering a “severe head injury” in his defeat by Serge Ambomo in Sheffield on Friday night.

The 29-year-old was knocked down in round two and the fight was stopped in the sixth, after which Wilson was treated at ringside and given oxygen.

“Jerome unfortunately suffered a severe head injury during his fight,” said his promoter Dave Coldwell.

“He is receiving the best possible care.”

Ambomo reportedly knelt down over Wilson and kissed his head after delivering the knockout blow, unaware that his opponent was seriously hurt.

The Cameroonian’s trainer Glyn Rhodes then intervened and put Sheffield-based Wilson in the recovery position.

Father-of-one Wilson was initially said to have arrived at hospital in a “responsive state”.

London Olympian Ambomo, 28, who had previously beaten Wilson in May, later apologised.

Before Friday’s fight, Wilson had a record of eight wins and two losses since his professional debut in February 2010.
