The air ambulance was called to Stamford Belvedere’s cup match on Saturday when midfielder Pete Conneely had his leg cut open down to the bone in a 50/50 tackle.
Pete walked off the field not realising the seriousness of his injury but was quickly in trouble because of the large quantity of blood he was losing.
Stamford Bels’ manager, Pete’s dad Martin, said: “He went in for a challenge and the opposition player must have been wearing blades.
“It ripped him clean open and he was losing a lot of blood.”
Bels committee members John Holland and Jon Morley helped stem the bleeding until an ambulance arrived.
The air ambulance landed on the pitch with 10 minutes left to play but in the end was not used.
Pete, 29, was taken to hospital to be treated.
Martin, who went with him to hospital, said luckily Pete’s bone was not damaged.
“They stitched his muscle up internally before stitching his skin,” he added.
Pete is now back at home resting. But the self-employed carpenter is unable to work with the injury.
Martin said: “We as a club will organise a fundraising night to help him out because he won’t be getting paid while he is off.
“It is something we do for any player in this situation.”
Martin added: “When he comes back will be a decision for him and his doctors.”
Stamford were 3-0 up in their PFA Challenge Cup match against Leverington Sports Reserves when the game was abandoned.
A brace from Chris Dakin and goal from Connah Hunt had given Bels the lead.
It has not yet been officially announced if the match result will stand.
