Broncos, Chiefs make moves

Posted by ESPN.com's Bill Williamson

The Broncos and the Chiefs shuffled their rosters Tuesday.

In Denver, the Broncos signed linebacker Mario Haggan, running back P.J. Pope and defensive back Roderick Rogers.

Haggan has spent the past five seasons with Buffalo and he played in 65 career games for the Bills. He was signed because weakside linebacker D.J. Williams is out for the next month with a knee injury. Pope and Rogers were on Denver's practice squad.

Pope was signed to the 53-man roster because Denver put running backs Michael Pittman and Andre Hall on the injured reserve, ending their seasons.

Denver cut tight end Chad Mustard and it added running back Cory Boyd and linebacker Tyson Smith to the practice squad. Boyd, a South Carolina product, was Tampa Bay's seventh-round pick this year.

In Kansas City, activated wide receiver Kevin Robinson and tight end Michael Merritt. Both players are rookies. Robinson was a sixth-round pick from Utah State and Merritt was a seventh-round pick from Central Florida. Both players have been on injured list.

The Chiefs could still try to sign a running back with Kolby Smith out for the season with a knee injury.
