Broncos waive three more to reduce to 75

Gary Kubiak and the Broncos’ coaching staff went home Monday night still facing difficult decisions and having little time to make them. Earlier that morning, they had trimmed their training camp roster of 90 men to 78, waiving nine, cutting one, trading another and placing a rookie on the injured reserve.

When they returned Tuesday, just hours before the 2 p.m. deadline to reduce the list to 75, Kubiak and Co. revealed the final three cuts.

Nathan Palmer’s work at Dove Valley is done. The third-year receiver, who spent most of last season on the practice squad, was waived. After one last practice, rookie linebacker Danny Mason and tight end Dan Light, a recent waiver claim, were sent home.

The three joined cornerback Tevrin Brandon, safety Ross Madison, guard Andre Davis, tight end/fullback Joe Don Duncan, quarterback Zac Dysert, punter Spencer Lanning, tight end Jake Murphy, running back Jeremy Stewart and linebacker Chase Vaughn on the first wave of cuts this week.

Chris Clark, a veteran right tackle, was traded to Houston for a seventh-round pick in the 2016 draft. Inside linebacker Reggie Walker was released. And Jeff Heuerman, the Broncos’ third-round pick who tore his anterior cruciate ligament in minicamp, was placed on the injured reserve.

The Broncos play their final preseason game Thursday against the Arizona Cardinals, giving 22 other players who survived the first round one last audition before the final group of 53 is selected by 2 p.m. Saturday. Ten of those might find their exit isn’t permanent; the team may begin selecting its practice squad starting at 11 a.m. Sunday.
