Kansas City, Mo. ? The agent for quarterback Trent Green said Thursday the Miami Dolphins have indicated “some flexibility” in their offer to Kansas City, but that he can’t get the Chiefs to respond.

A Chiefs spokesman said later, however, that the Dolphins remain inflexible in offering only a supplemental sixth-round draft pick for the two-time Pro Bowl quarterback. The Chiefs are believed to be asking for a fourth-rounder.

“Last Friday I made a call to the Chiefs to let them know I thought there was some flexibility, that we discussed what that might be, and if they were interested that I would carry that back to the Dolphins and see if we could put something together,” agent Jim Steiner told the Associated Press on Thursday.

“And I’ve yet to get an answer from the Chiefs.”

But Chiefs spokesman Bob Moore said the Dolphins had not budged.

“Miami’s made no offer. The last offer they made was a sixth-round pick,” Moore said. “It has nothing to do with Jim Steiner. Miami hasn’t changed anything. We haven’t talked to Miami in weeks. Miami has to cut the deal. Miami has to call the Chiefs.”

Green will turn 37 in July and is due $7.2 million if he stays with Kansas City this year. He asked permission to seek a trade when coach Herm Edwards said he wanted to reduce the overall age of the roster and indicated second-year man Brodie Croyle would be given every opportunity to win the job.

Steiner and Green have negotiated a contract with Miami, but the deal has been held up while the two sides argue over compensation.
