Jon Stewart's role with the Warrior Games will expand Friday night, as the comedian branches out from emcee duties into a brand-new gig: "SportsCenter" anchor.

Stewart, who hosted the Warrior Games' opening concert at Chicago's Soldier Field and also presided over last year's opening ceremony at the U.S. Military Academy, will co-host a special one-hour "SportsCenter" on Friday (7 p.m. Eastern) on ESPN airing from the United Center, where the medal rounds of wheelchair basketball and sitting volleyball will take place.

He'll be joined by Hannah Storm behind the desk, according to an ESPN news release. The pair also will be part of ESPN coverage of the games during the 6 p.m. Eastern hour, and Stewart will give an interview during the 11 p.m. "SportsCenter."

The Warrior Games are in their third year as a Defense Department-driven contest (previous years were run by the U.S. Olympic Committee) and their first in a large city. Wounded and otherwise injured athletes representing Army, Navy/Coast Guard, Air Force, Marine Corps and U.S. Special Forces Command teams are participating in Paralympic-style events, alongside teams from Great Britain and Australia. More than 260 service members will take part.

The eight-day event began June 30, but kicked off in earnest July 1 with the Soldier Field concert, headlined by Blake Shelton and Kelly Clarkson. Friday's United Center events mark the next-to-last day of competition; swimming events and a closing ceremony will take place Saturday.
