Safety Patrick Chung and right tackle Sebastian Vollmer were the only two New England Patriots who did not participate in Wednesday's practice, the team's first session this week before visiting Tim Tebow and the Denver Broncos on Sunday.
Chung, one of the New England secondary's most reliable players, has missed five straight games since injuring his right foot on Nov. 6 against the New York Giants. He compiled 55 tackles and one interception in New England's first eight games. He had been practicing with the team, but hasn't yet been cleared for games. The Patriots have fielded a make-shift secondary lately, with wide receivers Julian Edelman and Matt Slater taking a number of defensive snaps.
Vollmer has missed two straight games since suffering an injury to his right foot during New England's win against Philadelphia on Nov. 27. He has not practiced since the injury.
