Think before you tweet.

Notre Dame defensive tackle Jay Hayes could have used this advice before he fired off negative tweets criticizing his coaching staff Wednesday.

It seems Hayes was displeased with the amount of playing time he was receiving, so he took to Twitter to let out a little frustration. The tweets have since been deleted, but, of course, nothing ever leaves the Internet.

Head coach Brian Kelly announced Thursday the sophomore won't be playing this weekend because of his tweets.

"You have to think before you hit send, and what you have to do is knock on my door instead of hitting the send button," Kelly told reporters, per ESPN.com. "If he has a job at Google and talks about his boss that way, he probably is not going to have a job the next day."

Social media is fun, but you have to watch what you say because someone is always watching.
