Saints owner Tom Benson was recovering in a hospital on Friday after undergoing surgery to clean up a knee he was operated on in May, a team spokesman said.

Saints spokesman Greg Bensel said Benson "is doing great," though he could not attend the dedication of Tulane's new on-campus football stadium as he was scheduled to Friday.

Benson first had surgery on May 16 to repair a torn medial meniscus in his left knee. He then traveled to an NFL owners meeting in Atlanta during which Minneapolis was selected over New Orleans as the site for the 2018 Super Bowl.

Moving around with a walker, Benson fell and hit his head during the vote. He was checked out for a possible concussion and stayed overnight but was ultimately cleared.

The news about Benson's latest hospital stay follows two trips to an emergency room in West Virginia, where the Saints held a portion of training camp from late July to mid-August. In those instances, he was given oxygen and treated for dehydration as a result of symptoms related to the altitude of The Greenbrier resort, which is in the Allegheny Mountains.

Benson on Tuesday was present for the unveiling of a bronze statue honoring him outside the Mercedes-Benz Superdome. He was in a wheelchair and was brought to tears when he first saw the statue of him in a suit smiling and raising the Vince Lombardi Trophy after the Saints won Super Bowl XLIV on Feb. 7, 2010.

Benson planned to go Friday to Tulane's new Yulman Stadium for its dedication. He and his wife Gayle donated $7.5 million jointly to benefit its construction. The field at Yulman Stadium is called "Benson Field."

But Benson had his knee surgery between the unveiling of the statue and the ceremony.

Benson's Saints open the 2014 regular season at Atlanta at noon on Sunday. He will not be that game nor Tulane’s first contest at Yulman Stadium on Saturday at 3 p.m.
