Jofra Archer needed surgery for a cut on his hand after he dropped a fish tank whilst cleaning at home prior to travelling to India for the recent Test and white-ball series.

The Real Madrid forward missed a Champions League game due to an infection caused by shaving his legs. Boss Zinedine Zidane told reporters ahead of Real's 3-0 victory over APOEL Nicosia in September 2017 that Asensio would not feature because of a pimple which prevented him from pulling up a sock.
Wales hooker Baldwin sat out the Ospreys' PRO14 defeat against the Cheetahs in September 2017 because of a lion bite.

He later said he had needed four operations and was told he could have lost his hand.
Coventry goalkeeper Burge trained with a bandage on his head after he was struck by a puck while watching ice hockey in 2018. The then 25-year-old reportedly needed hospital treatment after being hit while he watched the Coventry Blaze's Elite League clash with the Sheffield Steelers.
Ryder Cup star Donaldson suffered a severe finger injury following a mishap with a chainsaw in January 2016.

Above the image, he wrote: "So folks in my time off decided to have a fight with a chainsaw and lost! Oops!!"
Frampton was forced to pull out of a fight against Emmanuel Dominguez in August after suffering a hand injury in what he described as a "freak accident".

Norway defender Grondalen, who played for his country from 1973 to 1984, probably had no concerns about his safety when he put on his running shoes and stepped out for a training run. However, while out jogging he collided with a moose and was forced to withdraw from an international as a result.
Former England goalkeeper James was never afraid of standing out from the crowd, but he brought himself unwanted headlines when he injured his shoulder while out fishing, causing himself pain when he tried to land a monster carp.

Australia paceman McGrath turned his ankle ahead of the second Ashes Test in 2005 when he stepped on a stray cricket ball during a warm-up game of touch rugby.

England batsman Roy missed Surrey's crucial Vitality Blast game against Glamorgan in August 2018 – and he had only himself to blame.
