After more than six months in exile, Brian Williams is set to return to MSNBC on Sept. 22, according to the network. He'll anchor live breaking news that day, which is expected to include coverage of the U.S. visit of Pope Francis.

Williams' return comes as MSNBC president Phil Griffin already has made some adjustments to the daytime lineup. Last July, Griffin canceled three afternoon programs — The Cycle, Now With Alex Wagner and The Ed Show — while announcing that Meet the Press moderator Chuck Todd would return to MSNBC to host a 5 p.m. show.

It's unclear if there will be changes to the primetime lineup, though the 6 p.m. time slot remains a work in progress as Al Sharpton's PoliticsNation was already moved out of that perch. (Sharpton's final show there was Sept. 4. He'll take PoliticsNation to Sundays beginning Oct. 4.)

MSNBC is expected to announce its 9 a.m. to 5 p.m. lineup soon. But Williams will not have a dedicated hour on the schedule, say network executives. Rather, he'll work on various afternoon programs as news warrants.
