Saints RB Khiry Robinson Takes Paintball TO THE FACE During Team Outing

It's all fun and games until someone gets shot in the face ... just ask New Orleans Saints running back Khiry Robinson who took a pellet to the grill during a paintball outing last week ... and TMZ Sports has the dramatic (hilarious) video.

It all went down this week at Paintball Command in Mandeville, LA where the Saints -- including QB Drew Brees and head coach Sean Payton -- gathered for a team-building paintball outing.

The video is pure hilarity, showing Khiry woofing and talking trash Tony Montana-style ... only to end up like Tony did -- on his back.

You can hear staff member Angel Santiago SCREAMING for everyone to stop shooting once he realizes Khiry got blasted -- and you can see the paint all over Robinson's face.

But don't worry ... we're told Khiry wasn't hurt at all -- and got back to paintballing right away.

For the record, we're told only one player complained about the pain from getting shot by a paintball -- Thomas Morstead ... who happens to be the kicker.
