Golf superstar Rory McIlroy sparked quite a bit of controversy last month when he made the decision not to speak to the media after all four rounds of the PGA Championship. And it sounds like the PGA Tour has some "concerns" about that move from the superstar.

Several high-profile golfers have opted not to speak to the media during recent tournaments. But Rory McIlroy’s decision to do so is particularly “concerning” for the PGA Tour, according to Golf Channel reporter Rex Hoggard.
