The 2012 Denver Broncos minicamp is about to get under way, but the mile high team will possibly be sans three of their players. The trio of K Matt Prater, QB Brock Osweiler and RB Ronnie Hillman remained unsigned heading into minicamp and may not participate in the team's first mandatory practices -- unless something changes soon.

The 28-year-old Prater finished the 2011 NFL season with a 76 percent success rate, hitting on 19 of his 25 attempts, and he sports a 78.4 percent rate on his career, including a 10 for 13 record from beyond 50 yards. Denver extended a franchise tender to Prater in lieu of a multi-year extension, but the veteran kicker has yet to sign the offer.
