Celtic are now just four wins away from the title after Saturday's bad-tempered 1-0 win over Aberdeen.
Alan Thompson's first-half penalty gave Celtic the victory, but the bad blood between the two sides resurfaced again late on when both Thompson and the Aberdeen substitute Hicham Zerouali were sent off after an off-the-ball clash.
Eugene Dadi was adjudged to have held Stephen Crainey down in the box in the final seconds of the first half and Thompson fired low into the bottom corner from the spot.
Two second-half goals from Andy McLaren enabled the new Kilmarnock manager, Jim Jefferies, to celebrate victory in his first game in charge with a 3-2 victory over Dundee.
The former Killie manager, Bobby Williamson, celebrated his first game in charge of Hibernian with a 3-0 win over the bottom side St Johnstone. The victory virtually secures Hibs' top-flight survival – their lead over St Johnstone has now stretched to 12 points, leaving the Perth outfit with little chance of avoiding relegation.
An Ian Murray brace gave Hibernian the advantage before Garry O'Connor sealed the win with a superb strike after the break.Reuse content
