An already-large card may have just grown by about 500 pounds, as the Las Vegas Review-Journal is reporting Alistair Overeem and Antonio Silva are set to square off.

UFC 156 goes down February 2 from Las Vegas. The main event is set to feature UFC featherweight champion Jose Aldo going up against ex-UFC lightweight champion Frankie Edgar.

Overeem is set to appear before the Nevada Athletic Commission in late December to re-apply for his fight license. Overeem, a former Strikeforce heavyweight champion, was suspended following a failed pre-fight drug test.

Silva defeated Travis Browne to earn his first UFC victory recently.
