Heacham came from three goals down to give Wroxham the fright of their lives in the Norfolk Senior Cup on Saturday.
The Magpies' Thurlow Nunn Premier Division hosts coasted into a 3-0 lead inside the opening hour after skipper Ed Tann was forced off with an injury early on with suspected ligament damage in his knee.
But Heacham, who could have taken the lead early on in the tie had it not been for a last-gasp clearance from Tom Huckerby, refused to buckle despite three leagues separating the two teams.
Efforts from Royce Rawlings and Joshua Winner reduced the arrears and, in between Heacham's two goals, substitute Fletcher Toll saw a shot come back off the post.
Heacham boss David Griggs said: "Even when we were 2-0 at half-time we couldn't fault the players and told them to carry on enjoying it.
"The first hour of the game was a reflection of the gap between the two sides and it would have been easy for us to crumble.
"But we kept going and I think if there had been another five or ten minutes then we might have been able to get a result.
"On the day we took two out of four of our clear chances and they scored three out of three.
"They were more clinical than us and they were also better on the ball, but you expect that with the level they are playing."
As well as losing the influential Tann, Heacham's injury woes continued with Isaac Linford also suffering a suspected broken wrist after landing awkwardly on his arm.
