Brennan's broker, Ryan Tollner, issued a statement that said Brennan was transported to Honolulu for further medical treatment after being taken to Kona Community Hospital on Friday. Tollner said Brennan's condition was serious.
Great Island police say Brennan was a passenger in an SUV driven by Shakti Stream. They say she crossed the centerline on Queen Kaahumanu Main road near Makalawena in North Kona and collided head-on with saloon driven by a Waikoloa woman.
Stream was also taken to Kona Community Hospital, while the other woman was transported to North Hawaii Community Hospital.
Brennan was released by the Washington Redskins this year.
