Alistair Johnston is out of Celtic's Scottish Cup tie against St Mirren this weekend.

The defender suffered a sickening head injury in the early stages of the Hoops' 2-1 win over Hibernian on Wednesday night.

The Canada international won his side a penalty after Hibs' Nectarios Triantis collided with him in the air. 

It came at a cost though, as the right-back, 25, was substituted off, with Anthony Ralston deputising in his absence.

Johnston was rushed to hospital for checks - but he gave the thumbs up to fans on social media after Adam Idah secured the victory at Easter Road with his second spot kick of the game. 

However, now, Rodgers has revealed to the media that the defender suffered a suspected fracture and will therefore miss Sunday's fifth round tie in Paisley.

Elsewhere, regarding team news for the match against the Buddies, South Korean duo Yang and Oh are back in contention after their involvement at the Asian Cup.

The pair join Japanese forward Daizen Maeda in arriving back to Scotland, meaning they're available for the champions once again.

Meanwhile, Celtic and Rangers used to be miles better than Aberdeen - but not anymore.

That's the view of new Dons manager Neil Warnock.

The veteran Englishman took over from Barry Robson at Pittodrie earlier this week as he got to grips with Scottish football in his first game at Ibrox on Tuesday night.

That ended in a narrow 2-1 defeat, as Philippe Clement's side went level on points with Celtic at the top of the Premiership for 24 hours.

Brendan Rodgers' side then opened up a three-point gap with victory over Hibernian, however, the Light Blues do have a game-in-hand. Aberdeen managed a 1-1 draw against Celtic last weekend on their own patch with Peter Leven in temporary charge.
