A medical examiner said Monday that Mina Brees, Drew Brees' mother, died Friday in western Colorado, but the cause of death is still under investigation.
Grand County chief deputy coroner Cindy Eller said Mina Brees died there, but Eller declined to identify the town or release any other information.
Grand County is in the mountains about 50 miles northwest of Denver and includes the western part of Rocky Mountain National Park and the Winter Park ski resort.
Drew Brees was practicing with the Saints on Monday in Metairie, La., after missing a scrimmage Saturday to gather with family.
"It was a long weekend. It was a tough weekend," Brees said after practice Monday evening.
Brees said he did not have any updates regarding the cause of his mother's death and indicated he'd rather not discuss the matter at length, at least not publicly.
"I appreciate everybody giving their condolences and everything, but ... I'd rather deal with it, move on, and I'm trying to," he said.
