Aberdeen goalkeeper Jamie Langfield is recovering in hospital after suffering a seizure on Monday.
The 31-year old is said to be in a stable condition and is now awaiting results of some tests undertaken.
"Obviously this is an extremely worrying time and the thoughts of everyone at the club are with him (and his family)," Dons chief executive Duncan Fraser told the club's official website.
"Jamie has had a comfortable night and there have been no further setbacks but until the results of the tests he has undergone are known, we are not in a position to comment further."
