Adrian Lewis and Jose Justicia had to be separated by stewards at the conclusion of their quarter-final match at Friday’s UK Open qualifier.
Lewis, 33, defeated Justicia 6-5 in a deciding leg which set up a semi-final contest with Michael van Gerwen at the Robin Park Tennis centre, but the match was marred by incidents both during and after the contest.
Two-time world champion Lewis confronted Justicia during and after the eighth leg, including directing some expletives at the Spaniard.
Following the match, Lewis pushed Justicia away at the neck, leading to tournament officials to step in and escort ‘Jackpot’ away.
The pair could face further ramifications from the Darts Regulation Authority after the incidents were referred by the Professional Darts Corporation.
A PDC statement read: “The incidents which occurred during and at the end of the Adrian Lewis v Jose Justicia quarter-final match at today’s Coral UK Open Qualifier have been referred to the Darts Regulation Authority for immediate consideration.”
