RIO FERDINAND begged to be subbed during a Man United Premier League game — because he had the runs.
The England star’s team-mate PATRICE EVRA also had to be replaced due to bad guts.
Live TV viewers and a sell-out 75,000 Old Trafford crowd were left baffled by the pair’s rapid and embarrassing exits with no obvious sign of injury.
Boss SIR ALEX FERGUSON has never revealed what had afflicted £30million Rio, 29, and £5.5million Evra, 26.

But United coach BRIAN MCCLAIR, 43, has now come clean about the incident in the 2-0 victory over Fulham on December 3.
The defenders were ill after a dodgy lasagne and had assured Fergie they could get through the game.
But McClair revealed: “Both players had upset tummies. If they hadn’t run off pretty sharpish, the pitch may have had some unexpected fertilisation.”
