Rory McIlroy did not take missing the cut at the RBC Canadian Open lightly, as he expressed his concerns about his game ahead the upcoming US Open.

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.

Rory McIlroy made an 8 on his fifth hole Friday at TPC Toronto, free-falling down the RBC Canadian Open leaderboard. After hitting his tee shot into the right rough on the par 4, McIlroy's approach shot from 134 yards traveled 165 — so far past the spectators around the green that they didn't notice it soar over their heads.
