Officials say two other members of the 20-member Bonneville Hotshots based in West Valley City, Utah, received minor injuries in the same incident on Saturday.
Trinity Ridge Fire spokesman Michael Williams says the hospitalized firefighter received chest, elbow and wrist injuries. He was expected to be released from the hospital Sunday but not return to firefighting for three weeks.
Williams says the crew was taken off the fire Saturday but returned to firefighting Sunday. A review of the incident is planned.
Earlier this month a 20-year-old Idaho firefighter was killed in northern Idaho by a falling tree.
