Rangers face an anxious wait to discover the extent of an injury picked up by teenage defender Danny Wilson.
The 18-year-old suffered a knock during a practice match with Celtic at Murray Park and will go for a specialist scan today.
Reports suggest the young centre-half could be sidelined for the remainder of the season and miss the Scottish champions' final four games as they edge closer to retaining the Clydesdale Bank Premier League title.
But, according to the club's official website, the full extent of the problem will not be known until after the scan. Wilson has enjoyed an impressive debut season for Rangers and has made 24 appearances so far, including Champions League and Old Firm fixtures.
He was a regular in the heart of defence alongside David Weir, until Madjid Bougherra's recent return from injury.
His displays have attracted interest from south of the border, with Liverpool among his admirers. Wilson was named Rangers' young player of the year at the club’s annual awards on Sunday.
The league leaders could secure their second consecutive SPL title with a victory at Easter Road on Sunday.
