Here's the real reason Tiger Woods has tape on his neck at The Open

Tiger Woods arrived at Carnoustie on Thursday afternoon with tape on his neck as a result of a sore neck from a "bad pillow" on Wednesday night.

Woods, who has had four back surgeries in recent years, was spotted with kinesiology tape (or KT tape) on his neck en route to shooting a level-par 71 on day one of The Open at Carnoustie.

The 14-time major champion, who is bidding to lift the Claret Jug for the fourth time in his career, got off the perfect start on day one with birdies at the first and fourth, but stumbled coming home with three bogeys and a birdie to fall back to where he started the day. 

But all the talk among Woods' opening day evolved around the tape on his neck, which was quickly cleared up in a tweet from ESPN's correspondent Bob Harig...

Not real easy to see the tape on the back of Tiger's neck but it is there. Apparently due to a sore neck from a bad pillow. Not believed to be serious. But we will have to get that clarified from him after the first round. Tiger has noted bad... pic.twitter.com/GR4a3FqcMW
