Ray Rice

Janay Rice tells ‘Today’ show: Goodell not honest: Janay Rice says NFL Commissioner Roger Goodell wasn’t being honest when he said Ray Rice was “ambiguous” about hitting her in a casino elevator.

“I know for a fact ... that Ray told the honest truth that he’s been telling from February,” Janay Rice told NBC’s “Today” show in an interview that will be broadcast Monday. A second segment will be shown Tuesday.

As for Goodell, she said: “I can’t say he’s telling the truth.”

An arbitrator Friday threw out Ray Rice’s indefinite suspension, making the former Baltimore Ravens running back a free agent. Former U.S. District Judge Barbara Jones called Goodell’s decision in September to change Rice’s original suspension from two games to indefinite “arbitrary” and an “abuse of discretion.”

The Rices met with Goodell in June. He then issued a two-game suspension but increased it to indefinite after an in-elevator video of Rice striking his then-fiancee in February was made public. “I think they did what they had to do for themselves,” Janay Rice said, referring to the NFL.

Goodell started Rice’s appeal hearing on Nov. 5 with more than two hours of testimony. Ray and Janay Rice testified the following day.

In her interview with “Today” host Matt Lauer, Janay Rice said she was furious with Ray but never considered leaving him.

Rice, a three-time Pro Bowl player during six seasons with the Ravens, hopes to return to the NFL. It’s uncertain whether a team will sign him this late in the season.
