ESPN posted a video Tuesday of WWE superstar Brock Lesnar at ESPN studios manning the security gate. This was quite a surprise to many of the employees entering the facility that day.

WWE announced this week that Jonathan Coachman and ESPN SportsCenter will be on hand this coming Sunday to cover WWE's Summerslam event live from Barclays Center in Brooklyn NY. This will mark the first time ever that ESPN's long running sports show will be on hand for a WWE event. Brock Lesnar takes on The Underatker in their long awaited rematch this Sunday.
