New England Patriots running back Brandon Bolden sprained his ankle last winter and was unable to run during any part of the team's offseason training program, according to league sources. Patriots running back Brandon Bolden is recovering from a sprained ankle that has prevented him from running at all this offseason. As an undrafted rookie last year, Bolden showed flashes of potential, gaining 274 yards on 56 carries. He is scheduled to meet with team trainers on Monday and believes his ankle has healed sufficiently, according to a source. Being that it was the offseason, New England opted to be cautious with him, holding him out of drills with the hope of having him ready for summer training camp.
