Rory McIlroy's Masters chances just took a major hit

Rory McIlroy is playing brilliant golf leading up to the Masters with a career Grand Slam on the line, but his quest for a green jacket has hit an untimely snag.

After wrapping up a T5 finish at the Texas Children's Houston Open, McIlroy revealed he's dealing with a right elbow injury with the first major championship of the season right around the corner.

"My right elbow has been bothering me a little bit, so I'll get some treatment on that and make sure that's OK going into Augusta," McIlroy said after shooting a final-round 64, per ESPN. "I still feel like I've got some stuff to work on. I still don't think my game is absolutely 100 percent under the control I would want. I've got my coach, Michael Bannon, coming in [Monday] so we'll be working at home and making sure the game feels good going into the Masters."

It's hard to believe McIlroy is having doubts about his game considering how in control of his golf swings he's been all season. In five PGA Tour starts this year, the Northern Irishman has two wins and no finishes worse than T17. He ranks first on Tour this season in total strokes gained, strokes gained from off the tee and scoring average.
