Former NFL quarterback Brett Favre is on this week's cover of Sports Illustrated.

These days 45-year-old Brett Favre, who is on the cover of this week’s Sports Illustrated, is a whole lot grayer, a little heavier, a grandfather of two and enjoying a somewhat relaxed life on his 465-acre estate in Sumrall, Miss.

Favre’s messy exit from the Green Bay Packers after the 2007 season and subsequent making up will culminate with the retirement of his No. 4 jersey and his induction into the team’s Hall of Fame on July 18.

Favre, who still holds NFL records for wins as starter, completions, attempts, yards, times sacked, and most passes intercepted, donned that No. 4 Packers jersey for this week's "Where Are They Now?" issue. It's first time that Favre has worn that dark green jersey since Jan. 20, 2008, when his last pass as a member of the Packers was intercepted during an overtime loss in the NFC championship game.

​​​The day after the SI photo shoot, Favre reflected on wearing No. 4 again.

"It was so big on me,” Favre says. “It felt like a nightgown. That’s not my world anymore."
