Rory McIlroy, Jon Rahm and Brooks Koepka have been grouped together for this week's Charles Schwab Challenge as the PGA Tour makes its comeback.

Golf's premier tour has been on hold since March when The Players Championship at TPC Sawgrass was scrapped after one round amid the coronavirus pandemic.

McIlroy, Rahm and Koepka – the top three ranked players in the world – were the headline group at that tournament in Florida and the trio will get another up-close view of their rivals' games on Thursday and Friday this week.

The Charles Schwab Challenge in Texas was originally scheduled for May but will now mark the PGA Tour's restart in an event held without fans present.

McIlroy, currently the world number one, has never played in the tournament at Colonial Country Club, while Rahm and Koepka have both finished in the top five in previous years.

American trio Rickie Fowler, Justin Thomas and Jordan Spieth have also been grouped together, as have Bryson DeChambeau, Dustin Johnson and Justin Rose.

Defending champion Kevin Na will play alongside Phil Mickelson, a two-time winner at the event, and reigning U.S. Open champion Gary Woodland.
