George Foreman will serve as a judge on the upcoming second season of ABC's American Inventor, according to Variety.

The former heavyweight champion , Foreman (who's better known these days for the electric grills that bear his name) joins American Inventor as the series gets an overhaul in time for its second season.

Additionally, entrepreneur and former talkshow host Pat Croce and inventor Sara Blakely have been added to American Inventor. The three new judges join one holdover from last year, U.K. mogul Peter Jones (who's also one of the show's executive producers).

American Inventor, which returns Wednesday, June 6 at 9 p.m., has also tapped a new host. News anchor-reporter Nick Smith (most recently a host at ABC's San Francisco station, KGO-TV) replaces Matt Gallant.

Beyond the host and judges, executive producer Clay Newbill said the show's structure has changed. The first six weeks of American Inventor will now take place on the road, as each week a finalist is chosen from one of six cities: Los Angeles, San Francisco, Chicago, New York, Orlando and Houston.

In week seven, a two-hour episode will follow the six finalists as they build their prototype invention and deliver it to the judges -- who then whittle the contestants down to three.

Then, with three left, viewers will pick their favorite invention. Winner will receive $1 million and a chance to mass produce their product.
