Anthony Stokes grabbed the only goal of the game as Celtic notched their seventh Premiership win in a row against 10-man Motherwell.
The champions dominated throughout the match, but were left frustrated by a mixture of poor finishing and great goalkeeping.
In the end, Stokes’ early strike proved to be the difference against a Well side who had Simon Ramsden sent off midway through the second half.
A late goal from substitute Ryan Christie ensured Inverness regained second spot as they came from behind to defeat Dundee 2-1.
Christie struck for John Hughes’ side with just two minutes left to complete their comeback after Billy McKay had equalised in 56 minutes to cancel out Greg Stewart’s opener.
