Johnny Manziel posts his phone number on Twitter

Cleveland Browns quarterback Johnny Manziel may have made the biggest social media mistake on Friday night.

Well, it's definitely debatable.

Manziel accidentally posted his seven-digit phone number on Twitter. The tweet was quickly deleted, but a screenshot of it lives on SI.com.

The phone number has an area code that includes San Antonio and Kerrville, Texas, where Manziel is from.

Manziel is still the backup quarterback for the Cleveland Browns, yet everything the former Heisman Trophy winner does is a hot topic on social media.

A call to Manziel's phone was not answered or immediately returned, but his mailbox is full.
