He'll play alongside Phil Mickleson and Justin Rose.
Rory McIlroy says he's still adjusting to a lack of fans at golf tournaments.
The world number one plays alongside Tiger Woods in the first two rounds of the Memorial Tournament, which starts today in Ohio.
Shane Lowry will begin his challenge around five past six this evening with Phil Mickleson and Justin Rose.
Graeme McDowell is also in the field.
McIlroy says it's important to get the competitive juices flowing:
15-time major winner Woods hasn't played since February due to a combination of back problems and the ongoing coronavirus pandemic.
He also says the new Covid-19 restrictions will take some getting used to, particularly playing without fans:
