A public memorial for Hall of Fame player and longtime NFL union head Gene Upshaw will be held Sept. 2 in Washington D.C., according to ESPN's Chris Mortensen.
The decision gives player representatives and rank and file union members a chance to attend the service, as Tuesday is normally an off day for players.
The NFL Players Association executive committee will have a players-only conference call Monday to discuss plans to begin the search for a permanent replacement for Upshaw.
On Thursday, the union appointed Richard Berthelsen as its interim executive director. Berthelsen, the NFLPA's chief counsel and Upshaw's top aide, has been involved in labor negotiations for 37 years.
Upshaw was remembered this weekend with a moment of silence at NFL exhibition games.
Upshaw, who served as the executive director of the NFLPA for 25 years, died Wednesday night of pancreatic cancer at his home near California's Lake Tahoe, just days after learning he had the disease. He was 63.
Upshaw's funeral is expected to be a private family service in California. Upshaw left a widow, Terri, and three sons: Eugene Jr., Justin and Daniel.
Among the few African-Americans to lead a major union, Upshaw guided players to the era of free agency and wealth beyond anything possible when he was a rookie in 1967. He also was criticized for maintaining ties to league officials and owners that some thought were too close, and for what retired players saw as inattention to their need for medical benefits.
As a player, Upshaw was an undisputed Hall of Famer, gaining entry as soon as he was eligible in 1987.
He played 15 seasons -- 307 games including exhibition, regular-season and playoff games -- all of them for a Raiders team that reached the Super Bowl three times and won twice. The Pro Football Hall of Fame posted a tribute to Upshaw, including his enshrinement speech.
