Philadelphia Eagles wide receiver DeSean Jackson has explained "frustration" was behind his sideline outburst at a teammate.
Fox Sports cameras picked up Jackson shouting at an Eagles colleague on the touch-line after a Nick Foles pass intended for Jackson was intercepted by Vikings cornerback Shaun Prater.
Jackson had to be restrained by teammates and coaching staff, and explained after the game what was behind his anger.
"Frustration," Jackson told ESPN. "It's part of the game."
The Eagles star felt he was open on the play, but by the time Foles got him the ball, Prater had closed the gap and picked it off on the Vikings 5-yard line.
Jackson's disgust was immediately obvious, he refused to chase back to defend the play and just threw his arms up in the air.
Eagles coach Chip Kelly was seen talking to Jackson after his outburst, and after the game he said he was trying to end the matter there and then.
"I just went over with Jason Avant and tried to squash it," Kelly said. "We'll get to the bottom of it."
The Vikings topped the Eagles 48-30 in Minnesota, despite the absence of star running back Adrian Peterson.
Foles, who has been a star for the Eagles since replacing Michael Vick at quarterback mid-way through the season, admitted he got the throw wrong to Jackson.
"It was just a bad throw," Foles said. "It was as simple sat that."
And the Eagles quarterback had no problem with his teammate's sideline objections.
"DeSean is a competitor and he wears his emotions on his sleeve," Foles continued. "He was frustrated with what was going on because he wants to win so badly and he wants to make plays so badly.
"I understand DeSean and I understand the frustration. You just let him cool down a little bit and then he is all right."
