EAGAN, Minn. -- Denver Broncos running back Mike Boone's thigh injury isn't as serious as the team initially feared when he left the practice field on a cart Thursday, but it could still impact the Broncos' decisions when rosters are cut to 53 players on Aug. 31.
A magnetic resonance imaging (MRI) exam revealed Boone, according to team sources, will miss a minimum of 4-to-6 weeks with the injury. He pulled up during a drill late in a joint practice Thursday with the Minnesota Vikings and was eventually taken to the locker room on a cart.
