Explained: The "peculiar" rules incident during round one of PGA Tour's Valspar Championship

PGA Tour golfers Rasmus Neergaard-Petersen and Isaiah Salinda were involved in a rarely seen rules incident during round one of the Valspar Championship on Thursday. 

The situation unfolded on the 16th, with both players out of position needing to get up and down to save par.

Neergaard-Petersen's approach ended up on the fringe, whilst Salinda's second finished on the front of the green. 

Given that he was further away from the role, it was the Dane's turn and he decided to putt from the first cut using his fairway metal. 

His birdie attempt lipped out but, just as it was coming to rest, collided with another ball. 

Turns out it was Salinda's and everyone was briefly confused. Both players and their caddies discussed the situation before calling for a rules official. 

During the broadcast, video analyst Orlando Pope explained the situation for viewers. 

"It is something you don't see a lot," Pope said, explaining that there would no penalty for either player. 

Pope said that Salinda would be required re-take his shot given that he was on the green whilst Neergaard-Peterson would play his third as it lies. 

"If the ball wasn’t played from the putting green, he would play as it lies," he said. "But since [Salinda's] ball was on the putting green he will replay that stroke.

"The ball he collided with, Neergaard's ball, that was chipped from off the green, he will play it as it lies. Very strange."

Sky Sports golf commentator Laura Davies chimed in: "[I've] never seen that before, no penalty I assume. He said you can just replay it. Peculiar."

Both players managed to escape with a par. 

Neergaard-Petersen eventually signed for a three under 68 to sit comfortably inside the top 10 whilst Salinda has a battle to make the cut on day two after returning a card for a 75.

South Korea's Sungjae Im set the pace on day one, carding a 64 to lead United States Presidents Cup captain, Brandt Snedeker, by one stroke. 

Billy Horschel, Xander Schauffele, Aaron Rai and Matthew Fitzpatrick are among the notables also inside the top-10. 

The Valspar Championship is the final event of the Florida swing. 

Viktor Hovland is the defending champion.
