NFL investigating texts to Browns' sideline

The NFL has started an investigation into if text messages were sent to the Cleveland Browns' sideline during games, a breach of the rules, according to the league.

According to reports, former Browns offensive coordinator Kyle Shanahan was disturbed by the texts.

It was considered interference from the front office during games.

Though it's not clear who sent the messages and who received them, a team source said the messages were subject of discussion among some players and coaches late in the season.

"Unless specifically permitted by league rules, the use of cellular phones, smart phones, tablet devices, computers, wearable electronic devices such as Google Glass, and other electronic equipment by coaches, players, and other club personnel is prohibited in club-controlled areas including, but not limited to, sidelines and coaches' booths," the NFL rulebook states. "These restrictions apply from ninety (90) minutes prior to kickoff through the end of the game, including halftime. Coaches, players, and other team personnel are permitted to use such electronic devices in the locker room prior to kickoff and are permitted to use league-issued Microsoft Surface tablets throughout game day for viewing coaches' still photos."
