Roger Goodell testified under oath Wednesday for two-plus hours in Ray Rice's appeal hearing in Manhattan, sources told "Outside the Lines."

Goodell spent the majority of his time testifying under cross-examination by outside union attorney Jeffrey Kessler, sources said. The sources did not disclose what Goodell said under testimony, citing a gag order in the case.

Rice and his wife, Janay, attended the hearing, which began midmorning at the offices of former U.S. District Judge Barbara S. Jones. Jones, who will decide the appeal, ruled that all witnesses would be testifying under oath.

The Rices are expected to testify separately Thursday, the sources said.
