Stars competing in the Ryder Cup will need to be on their best behaviour or face disqualification from individual rounds or the entire tournament if they end up breaking the strict rules.
The Bethpage Black Course in New York is playing host to the 45th edition of the Ryder Cup, with Europe aiming to hold on the trophy it won at the 2023 tournament at Marco Simone Golf and Country Club in Italy.
To retain the famous trophy, Europe need to pick up 14 points overall, while the Americans will need to score 14-and-a-half points to win the tournament on home soil - with Europe having the upper hand early on.

Europe have a score of five-and-a-half points compared to the American score of two-and-a-half points following the first day of action on Friday.
The tournament is due to run for the rest of this weekend and climaxes on Sunday as Europe have made a good start to retaining their trophy.
As with any sport or tournament, there are rules for players to abide by or they face disqualification.
Naturally, there are rules in place for the Ryder Cup which players have to stick to - and there is no suggestion at this point that any rules have been broken by any of those taking part.
The tournament is governed by the Official Rules of Golf, which were drawn up by the USGA and the R&A.
It means that players can be handed penalty strokes, forfeit a hole and face the prospect of disqualification for a range of rule breaks.
These include using prohibited equipment, playing from an incorrect position and signing the wrong scorecard.
Match officials also have the ability to disqualify any players who are deemed ineligible for competition, or those who they believe have committed either unsporting behaviour or a major rule breach.
This could be disqualification from individual rounds or the entire event, if the rule breach is deemed to be serious enough to merit the drastic decision.
No players have yet been disqualified from the Ryder Cup - but that is not to say it could never happen, and there's a first time for everything.
