CHARLOTTE, N.C. -- The older brother of Carolina Panthers coach Ron Rivera died Tuesday after an almost two-year bout with pancreatic cancer.
Mickey Rivera was 56.
A team official said the organization's thoughts first and foremost are with Ron Rivera. The official also acknowledged that because Mickey's home and family are in Reno, Nevada, Ron Rivera might miss the start of training camp to attend funeral services.
Rivera tweeted about his brother's death on Tuesday.
Players report to Spartanburg, South Carolina, on Thursday, with the first practice set for Friday night at Wofford University's Gibbs Stadium.
Rivera told The Charlotte Observer in January that he found perspective in his brother's battle while the Panthers were going through a two-month losing streak and while he was dealing with the loss of his house to a fire.
Rivera was given a game ball after Carolina beat the Arizona Cardinals 27-16 in the NFC playoffs. He then gave the ball to his brother.
"Knowing what he's been battling and going through, any of the problems I've had -- even this fire -- seem insignificant," Rivera told the newspaper at the time.
Secondary coach Steve Wilks would lead the team in Rivera's absence. Promoted to assistant head coach in February, Wilks ran practice on the final day of minicamp in June so Rivera could attend the graduation of his daughter from UCLA.
Wilks also handled many of Rivera's duties while Rivera dealt with his house fire last season.
