ENGLEWOOD | Broncos coach Vance Joseph’s first training camp got off to a rough start with word that Devontae Booker, who was pushing to unseat C.J. Anderson as Denver’s starting running back, will undergo wrist surgery Friday and is expected to miss six weeks. Booker suffered a hairline fracture late in OTAs but he and the team thought it was just a minor sprain until the Broncos did X-rays Wednesday when he reported for his training camp physical.
