Conference North minnows Hyde, who play in the sixth tier of English football, posted the wind-up message this afternoon as Falcao closed in on Manchester United.
Hyde tweeted: "Sorry Tigers fans Falcao has just failed his medical here at Hyde Leisure Pool, he couldn't swim against the wave machine so the deal's off."
Falcao is set to secure a move to United tonight.
He will arrive on a season-long loan and wear the No.9 shirt at Old Trafford.
The Monaco star jetted in from France to undergo a medical and discuss personal terms earlier today
