He's 38 and hasn't played in the NFL in three years, but former Vikings receiver Randy Moss hasn't ruled out a return.

Moss, who works for Fox, appeared on the network's pregame show with host Curt Menefee on Sunday night and didn't douse cold water on speculation he could play again, according to profootballtalk.com

"I actually have not lost the itch," Moss said. "I've been working out with a few guys over the offseason. I have been retired for the last two years, but you never know."

Menefee replied, "That's not a commitment that you're gonna be here beside us the rest of the year. It doesn't sound like it. Are you thinking [about a return to football]?"

Said Moss: "Hey, I don't know. The sky's the limit for me, Curt. So we'll just have to wait and see."

The timing was interesting, given the fact that Green Bay Packers receiver Jordy Nelson suffered a knee injury Sunday that reportedly will sideline him for the season.

Moss also was mentioned last week as a possible replacement in Carolina for injured receiver Kelvin Benjamin.
