New Orleans Saints quarterback Drew Brees filed an affidavit in court in support of teammate Jonathan Vilma's defamation lawsuit against NFL Commissioner Roger Goodell.

NFL.com reported Brees filed the affidavit in Louisiana District Court on Saturday.

Saints interim coach Joe Vitt and head athletic trainer Scottie Patton have also filed similar affidavits.

Brees' affidavit explained the damage that would be done to the team and the New Orleans and Louisiana community if Vilma is forced to serve his one-year suspension.

"Having been in the NFL for 11 years, I have come to the understanding that great teammates make teams great," Brees wrote. "I believe that my teammates with the New Orleans Saints, through leadership by individuals including Jonathan, have a good understanding of our responsibilities to our organization, team, teammates, the City of New Orleans and the State of Louisiana.

"In my four years as a teammate with Jonathan, I have not seen anyone conduct himself with a higher degree of professionalism, work ethic, responsibility, and genuine care for his teammates."

Brees' affidavit was also critical of the league's investigation and sanctions taken against the Saints in the bounty scandal.

Vilma's punishment was the harshest against any player involved in the scandal. Brees claims in the affidavit that the allegation that Vilma was involved in a $10,000 payment to intentionally injure quarterback Brett Favre in the 2009 NFC Championship Game is not true.

"My understanding is that Mr. Goodell has accused members of our defense, including Jonathan, of engaging in a pay-to-injury program that involved offering financial incentives to teammates to intentionally injure opposing players," Brees wrote. "I have no knowledge of a pay-to-injury program existing, and have yet to personally see any evidence that would substantiate these allegations. In my four years as a teammate with Jonathan, I have found that he is a man of integrity who passionately plays the game of football within the framework of the rules and has respect for his opponents."

Brees also defended Vilma's off-the-field character, focusing on his role in helping New Orleans recover from Hurricane Katrina and Vilma's foundation that helps build schools in Haiti.

Vilma has a temporary-restraining-order hearing on Thursday to try to stall his suspension.

The Saints open training camp Tuesday.

--Dallas Cowboys quarterback Tony Romo expressed his support for troubled teammate Dez Bryant at a celebrity golf tournament on Friday in Lake Tahoe.

Bryant had turned himself in to police on Monday after a warrant for his arrest was issued that accused him of assaulting his mother.

"The one thing I know is that Dez knows I have his back," Romo told ESPN at the American Century Celebrity Golf Championship. "Dez knows I'll be there for him. Dez knows that I'm going to stick up for him."

Bryant was accused of grabbing his mother, Angela Bryant, by the shirt and hair, hitting her in the face with his cap, striking her repeatedly in the hands and wrists, and pushing her in the chest, according to the police report.

A Class A misdemeanor family violence charge was expected to be filed by the DeSoto, Texas, police department with the Dallas County district attorney's office Friday.

Bryant, 23, faces up to a year in jail and a fine of up to $4,000. He may also be fined or suspended by the NFL under the league's personal conduct policy.

"None of us are directly involved in what's going on in his life," Romo said. "So everyone, the speculation, the articles and things that are written are just people that are guessing. And they're going to have their opinions based on it but no one knows exactly the way that Dez grew up, the way that things have shaped his life and his difficulties."
