The Denver Broncos still have an interest in St. Louis tight end Daniel Fells and Dallas defensive tackle Jason Hatcher, but they are tight against the salary cap and it might stall the team’s attempt to sign them, according to an NFL source close to the situation.

The Broncos wanted to sign both players on their visits Friday, but didn’t have the cap room to do it. The Broncos have other priorities and want to make sure they can sign those players first. ESPN’s Adam Schefter reported Friday that Denver agreed to terms with running back Willis McGahee. But that deal is not final because of Denver’s cap situation.

The Broncos have been handcuffed because a proposed trade of quarterback Kyle Orton to Miami didn’t happen. The Broncos still hope to trade Orton to clear cap room.

I wonder if the Broncos rue the decision of former coach Josh McDaniels to extend Orton’s contract another year last summer? Had McDaniels -- who made many questionable managerial decisions in his 23 months in Denver -- not extended Orton, Denver would have the necessary cap room to sign players and it would have the clarity at the quarterback position it currently doesn’t enjoy.

Meanwhile, the Denver Post reports former Oakland and Carolina defensive end Tyler Brayton could reunite with new Denver coach John Fox.

UDPATE: The Denver Post is reporting the Broncos will visit with Ty Warren, who was just cut by the Patriots. I could also see him getting interest form the Chiefs. Warren has New England connections to Kansas City general manager Scott Pioli and defensive coordinator Romeo Crennel.
