Ross County skipper Andrew Davies' chances of facing Celtic on Sunday - live on Sky Sports 2 HD from 12pm - are rated just 50-50, as the defender continues to struggle with a back injury.
Definitely missing out, though, are Jay McEveley (knee), Tony Dingwall (knee), Ian McShane (groin), Paul Quinn (hamstring), Chris Burke (illness) while Martin Woods is suspended.
However, Jim O'Brien is available for the Dingwall showdown after serving his own one-match ban.
Four points from their last two games have lifted County up to eighth place but with only three points separating them from a relegation play-off, boss Jim McIntyre knows there is no room for complacency.
He told the Press and Journal: "We must not fear the game - when we play against good sides, we want to test ourselves against players of that calibre.
"It's 11 versus 11 on the day and we know if we play to our best we've got a chance of winning the game. It's up to us to be as prepared as we possibly can, and we will be."
Brendan Rodgers has been freely rotating his Celtic squad since they secured the title at Tynecastle two weeks ago and will have a weather eye on the Scottish Cup semi-final against Rangers next weekend.
Scotland forward Leigh Griffiths is back in the squad having missed three games while centre-half Erik Sviatchenko - who has started just seven of Celtic 's 13 matches since the new year - will be hoping for a recall at Victoria Park.
Rodgers said: "Between now and the end of the campaign, some of the players who have been on the outside will get some games and it's a chance to give one or two with knocks the right preparation.
"There will be some changes through the course of the season, but I don't give up places just for the sake of it."
