Childress: 'Stay tuned' on Favre situation

Can Brett Favre still be a great quarterback? Minnesota Vikings coach Brad Childress says he doesn't know, but to "stay tuned."

Childress says he called Favre last week. That's the latest update from Minnesota's coach, who didn't elaborate on the conversation. Childress sidestepped most questions about the quarterback's status Thursday, refusing to speculate while Favre officially remains retired.

The Vikings have one more organized practice this week, their last scheduled activity until training camp begins July 31. Childress declined to answer when asked if he needs clarity on the situation before then.

In a radio interview Wednesday, the coach said he's eager to see what Favre has left in his arm, which reportedly was surgically repaired after the end of last season.
