Tom Brady had a 10-hour appeal hearing on Tuesday to determine if his four-game suspension may be reduced by Roger Goodell.

Brady was suspended by the league for his role in the use of deflated footballs in the AFC championship game win over Indianapolis. He arrived at the NFL's Park Avenue offices Tuesday morning, as did attorney Jeffrey Kessler, who is leading Brady's defense.

"I think we put in a very compelling case," Kessler said, adding that no timetable on a decision by Goodell had been given.

No details of the hearing were immediately available but a source told ESPN's Adam Schefter that "Tom Brady's greatest ally today was Tom Brady."

Sources also told Schefter that Brady came off as very genuine, earnest, and persuasive, addressing every issue raised in the league-sanctioned Wells report.

One of the sources called it "an A+ performance."
