Celtic manager Martin O'Neill remains in hospital after undergoing what the club described as a "small procedure", with no details given about the nature of the operation. The 74-year-old is expected to be discharged within a day or two, and Celtic have asked that his and his family's privacy be respected while thanking fans for their support.

O'Neill was in the dugout as recently as Monday, when Celtic began their new Premiership campaign with a 1-0 home win over Dundee. He returned to the club last October following Brendan Rodgers' departure, briefly stepped aside for Wilfried Nancy before resuming charge after Nancy's sacking, and led Celtic to a domestic double before signing a permanent one-year contract in June with the backing of major shareholder Dermot Desmond.
