DT Ty Warren was absent for the beginning of Broncos OTAs on Monday. As was unsigned franchise player K Matt Prater, LB D.J. Williams and second-round DT Derek Wolfe. Warren is refusing to take a pay-cut, while the suspended Williams was in court in relation to his lawsuit against the NFL. Rules bar Wolfe from attending until his senior year of college is officially over. Prater is skipping all offseason activities as he angles for a long-term deal.
