LAKEVILLE — A 56-year-old Norwood man who was seriously injured Saturday in a bicycle accident during a fund-raising ride on Howland Road in Lakeville has been discharged from the hospital and is recuperating at home, Pan Mass Challenge officials said Sunday.

The injured rider was participating in the Pan-Mass Challenge, a statewide two-day fundraiser in support of the Dana-Farber Cancer Institute to fight cancer.

The Lakeville Fire Department was alerted to a bicycle accident at about 12:20 p.m. Saturday, Aug. 5 Responders were forced to navigate against the flow of bicycle traffic, support vehicles and other vehicles in the area to reach the injured rider, the department reported. 

The specifics of how the accident occurred are not certain, Lakeville Fire Chief Michael O’Brien said. No motor vehicle appeared to be involved, the chief said.

The injured man was being treated by event medical staff and a private ambulance crew when Lakeville Fire arrived.
