Jason Witten was downright PISSED the Redskins claimed Reuben Foster after TWO allegations of domestic violence ... saying, Washington "used horrendous judgment in claiming this guy."
It all went down in the fourth quarter of the Eagles' blowout win over the 'Skins on Monday night ... when Witten was asked on the telecast for his take on the Foster signing.
The ex-Cowboys tight end didn't hold back ...
"I believe the Washington Redskins used horrendous judgment in claiming this guy," Witten said ... "I understand that it's an ongoing investigation."
"But, my family has been affected by domestic violence. I understand the anguish that it causes. Young players just have to understand that there is no tolerance for putting your hands on a woman. Period."
The cause hits close to home for Witten ... his family was impacted by D.V. when he was a child -- and he now has a foundation that serves women and families that have experienced it.
