Celtic have been crowned Scottish champions for the fourth consecutive season and for the 46th time in their history following Aberdeen's 1-0 defeat at Dundee United.
A 5-0 trouncing of Dundee on Friday from Ronny Deila's Celtic had meant that Derek McInnes' side needed to win at Tannadice in order to take the Scottish Premiership title race to another week, but they were unable to recover from Robbie Muirhead's 13th-minute goal.
Elsewhere, Inverness Caledonian Thistle looked set to strengthen their grip on third place with victory at St Johnstone after Aaron Doran gave them the lead with his sixth goal of the season.
However, St Johnstone remain very much in the hunt for European football themselves and battled back to secure a share of the spoils courtesy of a thumping 82nd-minute header from Brian Graham.
