Tottenham's Serge Aurier and Moussa Sissoko have apologised for training together despite the coronavirus restrictions.
Right-back Aurier posted a video on social media - since deleted - of him wearing a mask while running shuttles and sitting next to midfielder Sissoko.
UK government guidelines say you can only exercise on your own or with people you live with.
"We wish to apologise for not setting the right example here," they said.
"We recognise that as professional footballers we have a responsibility to be role models, particularly during this uncertain period that everyone around the world is facing."
In a joint statement, they added: "We must all respect the government advice to minimise the number of lives lost during this pandemic.
"We cannot thank NHS staff enough for their tireless work at this time and we shall both be making a financial donation to show our support for their efforts."
It is the third time Spurs staff have been caught doing something similar.
Manager Jose Mourinho was pictured holding a one-on-one training session in a park with midfielder Tanguy Ndombele.
Team-mates Ryan Sessegnon and Davinson Sanchez have also been filmed running side-by-side.
