An investigation is under way after Celtic goalkeeper Lukasz Zaluska was assaulted in Glasgow by a man believed to be a Scottish Premiership footballer.
Zaluska, 32, was attacked on Ashton Lane in the west end of Glasgow while on a night out in the early hours of 20 October.
He is said to have suffered a head injury and blood loss during the incident but the full extent of his injuries are not known.
It is reported the goalkeeper was allegedly attacked a fellow professional footballer, who cannot be named for legal reasons. Two other Premiership players present at the scene were also questioned by police.
Officers said they had launched an investigation and were examining CCTV for evidence.
A spokesperson added: "Police Scotland are investigating a report of an alleged assault on a 32-year-old male in Ashton Lane, in the west end of Glasgow, in the early hours of Monday morning.
"Police inquiries are ongoing, including the monitoring of CCTV."
Former Celtic manager Neil Lennon was also attacked on Ashton Lane in September 2008 after his team beat fierce rivals Rangers 4-2.
Celtic have yet to respond to the reports surrounding Zaluska.
The Polish keeper, who is second choice at Celtic behind Craig Gordon, signed for the club from Dundee United in 2009.
