Sunderland defender Julio Arca has entered the pantheon of bizarre footballing injuries after a jellyfish stung him on the chest.
Arca joins a long and strange list
The Argentine was concluding a training session on the beach with a swim in the North Sea when he sustained the injury.
Arca suffered an allergic reaction and was admitted to hospital after initial treatment at the club training ground.
Speculation is rife as to the type of Jellyfish, with a Portuguese man-of-war among the favourites.
Sunderland club doctor David Gough said: "It's difficult to say what type of jellyfish it was.
"The fact that he has had such a reaction makes you think it was not the standard type found off the English coast.
"Occasionally you get Portuguese man-of-war jellyfish in these waters; and with the turbulent tides seen in recent weeks that is possible.
"Either way the treatment is the same and he'll be fine. The only difference is that if it was a man-of-war he might expect pain for 24 hours and a rash for up to a month."
Gough added on the club's official website: "We don't know if he'll be fit for Saturday, we'll be in a better position to say on Thursday."
The incident happened off Seaburn beach in Sunderland and manager Mick McCarthy admitted: "You certainly can't plan for this."
But Arca is far from the first footballer to by hit by a strange injury.
Spain goalkeeper Santiago Canizares missed the World Cup in 2002 after dropping a bottle of aftershave on his foot.
Watch out - these fellas bite
Likewise goalkeeper Dave Beasant, who damaged ligaments in his foot after knocking over a bottle of salad cream.
Chelsea keeper Carlo Cudicini injured himself reaching for the remote control and Rio Ferdinand injured himself simply by relaxing with his feet on a coffee table.
But one of the most remarkable must surely have afflicted Brazilian star Ramalho, who was in bed for three days after swallowing a suppository intended to treat a dental infection.
