Jamie Foxx has to end a live video feed when Jerry Jones starts talking about the size of Cowboys players' private parts

Dallas Cowboys fan Jamie Foxx was given more inside formation than he bargained for when he was allowed behind closed doors to watch a recent practice.

It has been a rocky start for the Cowboys who began the new NFL season with a win over the Cleveland Browns ahead of being handed a huge reality check by the New Orleans Saints last weekend, conceding 44 points.

The Cowboys have traditionally been strong at home under Mike McCarthy, but they were blown off the field by Derek Carr and the fast-starting Saints.

This week, superstar actor Jamie Foxx was allowed behind the scenes to watch his beloved Cowboys practice, with owner Jerry Jones giving him some inside information as both watched on.

Foxx was live streaming the behind the scenes moment, and Jones did not seem to catch on. While giving Foxx details about players, he added that one had an "eight and a half inch d***."

Foxx received the information pretty casually, nodding and giving a 'uhh huh,' but he wisely ended the live stream sharply when realizing it could get Jones in trouble.

Jones is known for his loose public appearances where he rarely holds back, but few knew he had that sort of information on players.

On the pitch issues

With the Cowboys struggling early in the season, particularly on offense, with the running game struggling to get going following the return of Ezekiel Elliot, Jones has responded to requests for America's team to sign a new running back.

He said: "Running back is just not on our radar as far as an area of interest. I must tell you, this is a little bit of a first for me, because I've never seen such made of our position and what we're doing at that position. Running back this year. Not having done this or not having done that at running back.

"We've got a pretty good contemporary of our competition (Derrick Henry) this week in Zeke Elliott. Both of these guys came out the same time. I'm pleased with what Zeke is doing." The Cowboys still have Dalvin Cook on their practice squad, an experienced player they could lean upon if issues continue.
