INDIANAPOLIS - Denver Broncos officials were planning to meet with potential free agent defensive tackle Gerard Warren’s agent on Thursday night, the first meeting since the team gave its initial proposal to Warren. Broncos general manager Ted Sundquist said he and director of football administration Mike Bluem were going to talk to Warren’s agent Joel Segal about details of a new contract for Warren, whom Denver acquired in a trade with Cleveland last year. Sundquist said he was confident Warren would return to Denver, and hoped a deal could be worked out by the end of the week. “We’ll get a feeling what his feelings are,” Sundquist said. “Our initial talks were pretty positive about the parameters.” Sundquist said he hoped to meet today with Ethan Lock, the agent for potential free agent offensive tackle Matt Lepsis. The NFL’s free agency period is scheduled to begin March 3. Sundquist said the initial proposal by the team to Warren was well received. “To this point I’d characterize everything as fairly positive,” Sundquist said. Calhoun’s change Brian Calhoun said when former University of Colorado coach Gary Barnett wanted to move him from running back to wide receiver, he decided to transfer to Wisconsin. In Calhoun’s one season with Wisconsin he rushed for 1,636 yards, added 571 receiving yards and decided to leave early for the draft. He said he still couldn’t understand why Barnett, who was fired after last season, didn’t want to keep him at running back. “You know, I’m still puzzled to this day,” Calhoun said. “I don’t even know how to answer that question. I don’t know. You’d have to ask him.” No update Drew Rosenhaus, the agent for Philadelphia receiver Terrell Owens, refused to answer questions Thursday. The Broncos have shown interest in Owens. Rosenhaus wouldn’t answer whether he thought Owens would be traded before he is released by the Eagles or how long it might take for his client to find a new team if he becomes a free agent. “That’s just the approach,” Rosenhaus said about not commenting on Owens.
