A GoFundMe appeal has been set up in memory of a 27-year-old rugby player who died during a match.
Arturas Rudys was the father of a two-year-old child Emilijus.
His girlfriend, Jolita, wrote on the fundraiser page that Mr Rudys "passed away very quickly" like it was "in a dream" while playing for Wisbech Rugby Club against Diss.
She also wrote: "It is a very hard time for us right now, I can't give up."
"I have to live and show the right path to the our child. I have never asked for money, but I want to reach out to you and ask for help."
It is understood that Mr Rudys - who was originally from Lithuania - went down during the match on Saturday afternoon and despite efforts of ambulance staff to resuscitate him on the pitch, he passed away.
The game Eastern Counties First Division match at the Chapel Road ground was abandoned.
Roger Pierson, from the Eastern Counties Rugby Union, said there had been a collision but that no head contact had been involved.
He said two of the Diss players who were medically qualified immediately went to the aid of the injured man but that he died on the pitch.
Mr Pierson described the tackle as a "rugby incident" and said everything was being done to support all the players involved.
"The RFU and the Injured Players' Foundation are already involved and that help will be offered to Wisbech and also to Diss rugby," he said.
The GoFundMe appeal in Mr Rudys' memory has already reached more than £13,000 - the target was £5000.

Flowers have also been laid beside the tree.
