Childress still unsure of Favre decision

Eight days before his team's first training camp practice, Minnesota Vikings coach Brad Childress said Thursday that he still does not know whether quarterback Brett Favre will return for a 20th season.

"I've said this and I really believe it even more right now," Childress said in an interview on KFAN-1130 AM. "It would not surprise me either way."

Childress visited Favre earlier this week in Hattiesburg, Miss., but apparently left without a firm answer on Favre's future.

Childress says he wants Favre to make the best decision for himself.

Childress said he is "not that worried" about Favre's surgically repaired ankle but said Favre must decide whether he is ready to commit to playing a full season.

"You're either all-in or not all-in," Childress said. "That's wherein the decision lies."

Childress says Favre is running stadium steps in a weighted jacket to slim down.

The Vikings open training camp July 30 at Minnesota State University, Mankato.
