Conan O'Brien, 46, is returning to nighttime TV on TBS, he confirmed to UsMagazine.com Monday afternoon.
He'll go head-to-head against Jay Leno and David Letterman: O'Brien's show will air at 11 p.m. Monday through Thursday, premiering after the World Series this November. George Lopez's Lopez Tonight will bump to midnight to accommodate O'Brien.
"I've gone from network television to Twitter to performing live in theaters, and now I'm headed to basic cable. My plan is working perfectly," O'Brien, who opens his comedy tour Monday, said in a statement, which ended speculation he'd go to Fox.

O'Brien stepped down from the Tonight Show in January after NBC revealed they would push it back to 12:05 a.m. so Leno could return to the coveted 11:35 p.m. slot.
Lopez doesn't mind being bumped for O'Brien.
"I can't think of anything better than doing my show with Conan as my lead-in," Lopez said in a statement. "It's the beginning of a new era in late-night comedy."
