Dave Roberts got through 31 years at "Action News." (You should look so good at 73.)

On his way to his last broadcast Friday -- with his family -- Roberts banged up his knee, which explains the cryptic remarks that Jim Gardner made on set, as well as the ice pack that could be seen on camera.

He limped through a sweet party that the station threw after the broadcast.

He's due to get an MRI tomorrow.

Roberts was replaced as master of ceremonies at today's Philadelphia Public Relations Association luncheon by former colleague Cecily Tynan.
