Brad Childress and Brett Favre talked twice this week about moving forward from their animated disagreement on the Minnesota sideline last week over the coach's suggestion his grizzled quarterback should come out of the game.

Does that mean the conflict is over? Perhaps, perhaps not.

ESPN, citing unnamed sources, reported that Childress and Favre have clashed over the in-game authority for calling the plays and audibles.

Yesterday, they both downplayed any lingering dissension over a heated discussion that took place during Sunday's loss to the Panthers.

Favre and Childress exchanged words in the third quarter with the Vikings leading, 7-6. Favre had been sacked four times and taken some vicious hits and Childress said he simply wanted to protect his quarterback. Favre refused to come out.

"I think it's all resolved, first of all," Favre said yesterday. "The fact that we've lost two of the last three - the frustration is going to show. It should."

Despite the report, Childress said he and Favre are on good terms.

"I feel like I have a good relationship with him," Childress said. "I don't think anything has really changed. Have we learned each other since September or August? I'm sure we have."

But some, including LeRoy Butler, who played with Favre in Green Bay, weren't surprised that Favre butted heads with Childress.

"Everybody in Minnesota knows that Brett Favre is running that organization," Butler told the Milwaukee Journal Sentinel.

In other news, Childress says he's confident in the team's plan to manage rookie Percy Harvin's migraine headaches, which have kept him out of one game and limited him to one practice last week.

Childress said yesterday Harvin recently had a "good" visit with specialists at the renowned Mayo Clinic in Rochester, N.Y. The coach downplayed the significance of bulging discs Harvin revealed he has in his neck, saying they're not herniated.
