Dedryck Boyata's suspension will be upheld after the Bhoys' appeal against his dismissal was thrown out.
Celtic have been dealt a blow in their attempts to keep ahead in the race for the Scottish Premiership title, with the Scottish FA confirming that the appeal against Dedryck Boyata's red card has been rejected.
The former Manchester City man was sent off in the 1-1 draw at Hamilton for a challenge he made whilst acting as the last defender.
However, the red card has been upheld by the SFA and the 25-year-old will miss Celtic's next league match away at Partick Thistle, although he will be available for Sunday's Scottish Cup quarter-final clash with Greenock Morton.
The 25-year-old defender has been an important player for the Bhoys this season since moving to Parkhead in June, scoring six goals in 37 appearances in all competitions.
Meanwhile, Celtic have faltered of late in their bid to stay ahead of Aberdeen at the top of the league table, drawing 0-0 at home to Dundee on Wednesday after being held at Hamilton.
The leaders are now just four points ahead of their nearest challengers with 10 matches of the season remaining after the Dons won 1-0 at Dundee United in midweek.
