Robertson suffers broken leg

St Johnstone's David Robertson has suffered a broken leg and will undergo surgery on Thursday, the club have confirmed on Twitter.

The midfielder left the field on a stretcher after coming on as a second-half substitute during Wednesday night's 1-0 defeat to Hibernian.

He was expected to spend the night in Perth Royal Infirmary following the Scottish Premier League clash at McDiarmid Park. The club has now confirmed initial fears of a leg break.

They wrote on Twitter: "Confirmed that @davidrobbo12 broke his leg in last nights game and is to undergo surgery today."
