Brett Favre is still mulling his NFL future, the quarterback's agent Bus Cook told ESPN.
Some reports projected Favre would reach a decision by Friday on whether he would sign with the Minnesota Vikings or stay retired, and while Cook told ESPN "he could," Cook added, "I think he's more likely to wait until the beginning or middle of next week."
Cook said that in a conversation with Favre on Friday morning, Favre was still considering all the mental and physical factors that would go into playing a long season as he turns 40 years old.
Cook also noted that before Favre can sign a contract, he would have to apply for reinstatement with the league. That can be handled in a letter faxed to the NFL offices, but it has not happened yet.
Vikings coach Brad Childress insisted this week he's not certain what Favre will decide, but team officials have contingency plans in place to deal with the expected surge in training camp fan attendance if Favre joins the team.
Some players have been calling and texting Favre to encourage him to sign up for at least one more season. But even those who actively want Favre on the team say they would like a firm answer sooner rather than later. Vikings players are required to report to camp at Minnesota State University in Mankato by next Thursday. Their first practice is the following day.
As one player who had been in a text conversation with Favre told ESPN, "By now you've pretty well got to know what you want to do, so let us know. We want you, but let's rock and roll. It's time to play football. Speculation time is over."
