Driver on ABC show on Tuesday night

GREEN BAY, Wis. -- Donald Driver played 14 years in the NFL and became the Green Bay Packers' all-time leading receiver in part because of how dedicated he was to taking care of his body.

Now, in his retirement, he's helping others do the same.

Driver, who retired following the 2012 season, is appearing tonight on ABC's "Extreme Weight Loss" program as a guest star and trainer.

On the episode, Driver will help a Milwaukee native named Cassie, who appears on the show in order to lose weight before she meets the son she gave up for adoption 18 years ago. Driver will be seen working with the show's regular trainers, Chris and Heidi Powell.

"He's a legend to me; he's a legend to this town," Cassie says. "He has all the values that I'm working on, and I know that he is going to help guide me, along with Chris and Heidi, to make me the best person I can be."

In a preview clip of the show, Driver says he's there to support Cassie and her husband.

"I'm going to mentor them," Driver said. "I'm here to support them. I'm not going to let them down."

The show can be seen at 8 p.m. ET on Tuesday on ABC.
