Transcript for Exclusive: Adrian Peterson Claims NFL Exec Promised Him 2-Game Suspension in Audio Recording
Now to suspended NFL star Adrian Peterson. The players' union expected to file a lawsuit on his behalf this morning. ABC news has a recording of Peterson and a top league official. Ryan smith is here with the latest. Reporter: Good morning, robin. NFL star Adrian Peterson claimed the league promised him a two-game suspension from the NFL not the indefinite ban he's serving now after losing his appeal on Friday. A league whose words betray their actions. I'm trusting you, brother. Can I trust you? Yeah, you can trust me. Reporter: This morning, did the NFL make a promise to vikings star Adrian Peterson that it didn't keep? I get the two games? Yeah. Reporter: Peterson's lawyers claim this November 12th phone call shows NFL executive troy Vincent promising spiterson a two-game suspension instead of the indefinite ban handed down just six days later. It will be two additional game, not time served. No, no, no, no. It won't -- the one this weekend. So really, it's just next week and you -- you -- you -- you -- you're rolling. You're back. Okay. Reporter: The six-time all-pro who pleaded no contest with no jail time for beating his 4-year-old son with a switch lost his suspension appeal Friday. At that hearing, his lawyers claim the league retaliated against the former NFL mvp for failing to meet with the league day before he was suspended. A meeting his lawyers say was not required under league rules. On that phone call, Vincent seems to say that meeting is key. Two games? Yeah, that is -- but you cannot -- you got to -- you've got to act -- just go through the process. Reporter: Later on the call, he seems to make a plea to the suspended superstar. I gave you my word the other day. I think we looked at each other and -- in my heart, I'm praying that we can just get your family restored and get you back on the field so that you can continue to be the ball player, the citizen, the father, the husband that god has called you to be. You've done a lot paid, paid the price. And I think everybody is -- everybody understands that. Reporter: At Peterson's appeal, Vincent denied making promises. Saying I didn't promise Adrian anything. The appeals officer appointed by roger Goodell agreed, saying Vincent wasn't speaking for the NFL but trying to help Mr. Peterson put this issue behind him and get back to his life, his family, and football. We reached out to the NFL for comment. It sent us to the appeal's officer's decision in which he said he did not have enough evidence to conclude it was retaliation against Peterson. And Ryan, from a legal standpoint, what is your take on all this? Reporter: I think the federal lawsuit will have a tough time. They have to prove serious misconduct on behalf of the appeals officer. Gnat that's a little bit far afield. This is the last chance to get him back this year. Thank you, Ryan. Now Amy has the other top stories.
