Motherwell have been found guilty of breaching SPFL rules on unacceptable conduct by supporters during last season's play-off final against Rangers.

Following an investigation, the league body has identified multiple failures by the club in dealing with supporters during and after the match, where police were forced to intervene after home fans invaded the pitch following Motherwell's 6-1 aggregate victory over the Ibrox side.

However, the club has not been punished at this time and has been given 18 months to deal with issues raised at the game and make change to their match organisation, security arrangements and supporter organisation.

The SPFL brought charges against the club last August and convened a commission to investigate whether the club had done everything it could to ensure good security and conduct at the high-profile end of season match.

The commission found that a series of failings on the Motherwell's part had contributed to the trouble.

In a statement issued by the SPFL, it revealed that ticketing arrangements had allowed Rangers fans to buy tickets in parts of the stadium reserved for Motherwell fans and that the steps taken to segregate fans had increased the likelihood of fans mixing.

The club was told that security arrangements were inadequate in preventing Motherwell supporters from entering the pitch at the final whistle and provoking opposition fans and noted that similar problems in previous years should have highlighted the need for more stewards.

The commission concluded that "Motherwell FC did not, so far as was reasonably practicable, ensure that incidents of unacceptable conduct did not occur at the match" and that the club had yet to show that it had taken action to identify and deal with supporters who caused the trouble, including those who invaded the pitch and the individual who threw a flare.

Though the league rules allow them to hand down a range of sanctions, Motherwell have been given an 18-month period to show that they have effectively dealt with the issues raised and changed match-day procedures to prevent the likelihood of any further trouble.
