After joining the Saudi-backed LIV Golf Invitational Series, Ian Poulter was among a handful of players to be barred by the DP World Tour from competing in the Scottish Open next week.
However, after appealing the ban, a hearing before Sport Resolutions (UK) on Monday resulted in a temporary reversal, meaning Poulter can rejoin the field.
Poulter was among three players to have their bans overturned, with Adrian Otaegui and Justin Harding also allowed to rejoin, pending determination of their substantive appeals.
DP World Tour chief executive Keith Pelley said: "Out of respect for JP and Noreen McManus, their wonderful Pro-Am and the outstanding fundraising they undertake on behalf of charities in the west of Ireland, I will not be giving a detailed response on this matter right now.
"I will simply say we are disappointed by the outcome of today's hearing, but will abide by the decision. It is important to remember, however, this is only a stay of the sanctions imposed, pending the hearing of the players' appeal as to whether those sanctions were appropriate.
"The make-up of the field for the Genesis Scottish Open will be advised in due course, but based on this decision the field size will increase beyond 156.
"We will make further comment on this in due course, but not during our time at Adare Manor."
As for Poulter, the 46-year-old felt he was left fighting "for his rights to play golf".
Speaking before the decision was announced, he said "I feel disappointed, I feel offended that obviously I'm suspended from playing golf on a tour where I've been a member for 24 years, but I've been told I can't, so it's disappointing.
"I've put it in as an individual because I want to play so whether people want to come in on the back end of that is up to them, but my correspondence is obviously fighting for my rights to play golf."
As it stands, Poulter is preparing to take part in the Scottish Open, with play starting this week on July 7.
