Rory McIlroy unintentionally accomplished something extremely rare on the golf course on Thursday: his 9-iron head broke off during a shot at the BMW PGA Championship.

Rory McIlroy once threw his 3-wood in frustration at the 2016 British Open at Royal Troon and broke it, and there was that time at the 2015 WGC-Cadillac Championship at Doral when he angrily threw his club in the lake on the eighth hole, but the club damage that happened on Thursday during the DP World Tour’s BMW Championship was not his fault.

Rory McIlroy lost the club head on his 9-iron and then lost the lead by going out of bounds on the last hole in shooting an eventful 5-under 67 in the first round of the BMW PGA Championship.
