Despite a switch in opponents, Polish light heavyweight standout Jan Blachowicz will still make his United States debut in Las Vegas on September 5, as he takes on Ultimate Fighter 19 winner Corey Anderson in a UFC 191 bout.

Blachowicz was originally slated to face Anthony Johnson, but "Rumble" will now meet up with Jimi Manuwa at UFC 191, with Blachowicz, winner of six of his last seven, ready to battle it out against Anderson, who has won two of three UFC bouts, stopping Matt Van Buren and decisioning Justin Jones.

Tickets for UFC 191, which is headlined by the flyweight championship rematch between Demetrious Johnson and John Dodson, are on sale now to UFC Fight Club members and UFC newsletter subscribers. Tickets go on sale to the general public at 10am PT on Friday, July 31.
