According to a report by Sherdog, Isaac Vallie-Flagg will not make his second UFC appearance next month, as the former Strikeforce fighter has suffered an injury.

Vallie-Flagg was scheduled to meet Sam Stout at UFC 161 in Canada on June 15. The card previously lost its main event in interim UFC bantamweight champion Renan Barao and Eddie Wineland.

A replacement for Vallie-Flagg (14-3-1) is underway to keep Stout (20-8-1), a native of Canada, on the card. The bout is set for the prelims.
