Los Angeles Chief of Police Charlie Beck broke his pelvis on a rocky trail in the Tehachapi Mountains Saturday in a dirt bike accident.
Beck, a competitive off-road motorcycle rider for 40 years, was riding dirt bikes with friends when the accident occurred, police said.
He fell on a rocky trail, fracturing his pelvis, but was able to ride his bike back to his truck.
He then received emergency care at a hospital.
"I want to thank everyone for their well-wishes as I recuperate from my recent motorcycle mishap," Beck said in a statement. "As always, I am in constant contact with my LAPD command staff and will be working diligently while I recuperate to continue leading the men and women of the LAPD."
He may require surgery on Monday, and is expected to recover, police said.
