Jon Rahm joked he has been brushing up on how things work in the courtroom by watching the hit TV show Suits as golf's civil war between the PGA Tour and LIV Series wages on.

The battle between the PGA Tour and the controversial Saudi-backed LIV Series took another twist last week when three defectors went to the courts in a bid to play in the lucrative FedExCup playoffs.

Talor Gooch, Matt Jones and Hudson Swafford had filed a restraining order to allow them to play this week's tournament, while 11 LIV Golf stars put together an antitrust lawsuit against the PGA Tour.

However, a judge ruled ahead of the FedEx St. Jude Championship that LIV Golf players were not eligible to compete in the playoffs.

Former world number one Rahm conceded he had only fortuitously seen the verdict but was happy with the outcome.

"Well, I can tell you I had zero attention on it. I only found out that it was going on because I walked by a player dining and I saw about 10 really nervous people pacing all around the room," he said ahead of this weekend's BMW Championship.

"I asked and heard what was going on. I was in the room when the judge made a decision known, but only because I was walking by and they told me it was time. So, I was like, 'I'll stay'.

"I think it could have made things a little bit awkward. They chose to leave the PGA Tour. They chose to go join another tour, knowing the consequences, and then try to come back and get courts and justice in the way.

"It wouldn't have sat extremely well with me but, at the same time, they're adults. They're free to do as they please to an extent. And that's what they chose to do if they're allowed by a judge. I'm nobody to say otherwise. Would it have been awkward? Possibly. But, I guess we'll never know."

Rahm does not foresee this being the end of LIV players' attempts to play in PGA Tour events and offered a little insight into how he has been brushing up his knowledge on legal proceedings.

"I am confident that the LIV side of things are still going to push strong to keep trying to change some things," he added.

"But I also know that the lawyers and the PGA Tour side are going to keep fighting to keep things the way are going right now.

"It's not the last thing we're going to hear from them. But I just started watching the show Suits. So, I'm kind of learning now about how what happens in a courtroom."

U.S. Open champion Matt Fitzpatrick also weighed in on the discussion, saying the time has come to put the focus back purely on playing golf.

"I'll be honest, I've not been asked much about it myself personally. So, it's just been it's been fine," he said.

"For me, it's just seeing it in the media and stuff. You just get fed up with talking about it.

"In my personal opinion, let's just get on with it now. We just want to play golf and concentrate on what we do. That's purely my take on that."
