UFC Tonight aired Tuesday evening and brought several worthy news items with it.

First, UFC 165 was announced for September 21 from the Air Canada Centre in Toronto. The card has no matches to date, but will likely feature a big-time main event, possibly Georges St-Pierre vs. Johny Hendricks.

It was also confirmed that Jorge Masvidal will replace Reza Madadi and face Michael Chiesa at UFC on FOX 8.

Madadi is having trouble with his visa and the UFC went ahead and replaced him with Masvidal.

Masvidal is a former contender to the Strikeforce lightweight title, holding a 24-7 record that includes a recent win inside the Octagon.

Chiesa is 9-0 in his career and has won each of his last five fights via submission. He is also a former winner of The Ultimate Fighter.
