CHARLOTTE, North Carolina (Reuters) -The PGA of America said on Saturday that finding driver heads that are non-conforming is not unusual and they have no concerns about player intent after Masters champion Rory McIlroy reportedly ran afoul of the rule at the PGA Championship.

According to a SiriusXM PGA Tour Radio report, McIlroy's driver was ruled non-conforming ahead of this week's major where he switched to a backup and made the cut on the number after struggling off the tee through the first two rounds.
