SPFL verifies title decider was completed prior to pitch incursion
Celtic secured a record 56th title at a lively Parkhead after beating rivals Hearts who only required a point to become champions for the first time in 66 years.
Callum Osmand sprinted clear to score in the eighth minute of added time to seal the victory sparking chaos on the pitch as ecstatic Celtic fans flooded onto the grass.
The contest was not restarted and Hearts released a statement on Saturday describing the events as disgraceful.
"We would also like to thank the referee and his excellent team of match officials for their calm approach on such a dramatic day," an SPFL spokesperson said.
"Given the speculation about the conclusion of the game we would like to confirm that prior to presenting the trophy we were advised by the match referee that the contest had finished and had not been abandoned.
"However we utterly condemn the scenes which saw a number of Celtic supporters enter the field of play. We await the report of our match delegate regarding any specific incidents that occurred but regardless supporters entering the field of play in any circumstances is wholly unacceptable and puts those taking part and working at a match at risk."
The Hearts players and officials departed the stadium within minutes of the game ending with the club stating it was due to a menacing and threatening atmosphere.
The Edinburgh club said it was in contact with Police Scotland over alleged verbal and physical abuse of some of their players by fans who had entered the pitch.
"Reports of serious physical and verbal abuse towards our players and staff both on the pitch and elsewhere are deeply disturbing," Hearts said. "We are investigating this fully and are in dialogue with Police Scotland.
"We expect the strongest action possible to be taken by the footballing authorities in the interests of protecting the safety of players and supporters and the integrity of our game."
Police Scotland confirmed they had made several arrests and that two officers had been injured during disorder as Celtic fans celebrated in the city.
