NORTON, Mass. (AP) — Brooks Koepka has withdrawn from The Northern Trust with what he described as nagging hip and knee injuries.

Koepka was No. 97 in the FedEx Cup standings and would have needed a good week at the TPC Boston to reach the top 70 and advance in the PGA Tour’s postseason. Koepka started the year ranked No. 1 the world but hasn’t won in more than a year.
