Just after 1 p.m., Chris Russo is scheduled to visit Mike Francesa's "Mike'd Up,'' Russo's first appearance on his old station in the 14 months since he and Francesa parted ways, ending a 19-year partnership.

Francesa is to return the favor at about 6:30 p.m. with a guest appearance on Russo's "Mad Dog Unleashed'' on Sirius XM Satellite Radio.

Both shows will originate from Yankee Stadium in advance of the Angels-Yankees game.

The joint appearances won't be the first for the old duo. Last night, Francesa called in to Russo's show as a surprise guest as part of the celebration of Russo's 50th birthday, which is Sunday.

The two spoke for 12 minutes, mostly about the baseball playoffs, falling comfortably into their old pattern of sports banter. The only reference to their changed circumstances came about a minute in, when Francesa took a gentle poke at Russo's lower visibility among New York-area fans, saying, "What happened to you now that you're 50?''

Russo laughed and said, "That's a good point. Where did I go?''

It has been a busy media week for Russo, who appeared on Don Imus' WABC radio show last Friday and with Howard Stern on Sirius XM and David Letterman on Wednesday.

Francesa and Russo have not spoken regularly in the year since they broke up, but they have been on friendly terms personally in recent months.
