Luke Littler was involved in another heated on-stage exchange on Thursday night after Gerwyn Price was forced to apologise during their dramatic Premier League Darts play-off showdown at London's O2 Arena.
The teenage sensation booked his place in the final after edging past Price in a thrilling last-leg decider, but not before tensions briefly flared between the two stars during a remarkable semi-final contest.
Price had looked destined for defeat when he trailed 9-4 before launching a stunning fightback to level the match at 9-9.
The Welshman produced one of the moments of the night in the 15th leg when he landed a spectacular 170 checkout - the highest finish possible in professional darts.
After pinning the iconic "Big Fish", Price celebrated by performing his trademark fishing gesture, mimicking the act of reeling in a catch.
However, the celebration appeared to irritate Littler, who had already stepped up to begin the next leg.
The Warrington-born star immediately voiced his frustration to referee Huw Ware after Price removed his darts from the board, with the official later stepping in to issue a warning.
Price quickly moved to defuse the situation.

The former world champion approached Littler following the leg, with the pair exchanging words before embracing in a show of sportsmanship.
The incident comes just weeks after Littler found himself at the centre of another on-stage dispute during his World Championship clash with Dutch star Gian van Veen.
That contest also featured visible tension after van Veen appeared unhappy with Littler's reactions during crucial moments of the match.
As van Veen missed a match-winning dart at double 15, television cameras captured an exchange between the pair before Littler gestured towards his opponent.

Back at the O2 Arena, Littler recovered from the Price controversy to secure victory and set up a blockbuster final against long-time rival Luke Humphries.
Humphries had also required a deciding leg to overcome Jonny Clayton in the evening's other semi-final.

The emotional teenager later broke down during his post-match interview with Sky Sports as he opened up on the pressures he has faced throughout the season.
"After Brighton I came off stage and the incident in Manchester (with van Veen)," Littler said.
"I was sat at home saying to Faith [Millar], 'I don't want to do it anymore, just the crowd every week'.
"I said to her I'm down bad."
As supporters inside the O2 Arena chanted his name, Humphries stepped in to console the 18-year-old.
Littler's partner, Faith, was also seen in tears in the crowd.
