Apparently not everything you read on the Internet is true.

One Kentucky fan proved that over the weekend when he posted a message on Facebook that Bobby Petrino had agreed to become the next Kentucky football coach.

As we all know, that's not the case.

The Advocate-Messenger reported that J.R. Greer is friends with a number of former Kentucky football players. So he told the paper he thought he would have some fun with them.

"I just decided to post Petrino was getting the job and figured my friends would get all riled up and react," Greer told the paper. "I never dreamed it would go outside my small network of friends."

According to the report, Internet message boards and radio talk shows ran with it.

Greer posted an apology Friday night: "I want to apologize that earlier I wrote that Bobby Petrino would be our next coach. My post was in humor as most all my post are (if not pictures of family or friends). We support UK and the Big Blue Nation and trust Mitch Barnhart will make the best hire possible for UK."

Greer, according to the report, said he "had hundreds of friend requests in a matter of minutes" from people looking for confirmation.

To be clear, Greer is not an ordinary fan. His father, Elmo, is regarded as a major UK booster, according to the report.

It was widely reported earlier this month that Petrino's father told the Louisville Courier Journal that the former Arkansas coach would be interested in the Kentucky job if offered.
