“Hot Sauce” fans will have to wait a little longer to see Trevor Smith return to the UFC octagon after a hand injury forced the middleweight out of his UFC Fight Night 83 bout with Leonardo Augusto Guimaraes.

The injury was confirmed by a source close to Smith (13-6 MMA, 3-3 UFC). The UFC is seeking a replacement to face Guimaraes (11-1 MMA, 0-0 UFC) on short notice.

UFC Fight Night 83 takes place Sunday at Consol Energy Center in Pittsburgh. Following early prelims on UFC Fight Pass, the remainder of the card airs on FOX Sports 1.

Smith is coming off a dominant victory over Dan Miller at the TUF 21 Finale this past July. After kicking off his UFC career with a split decision loss to Ed Herman at UFC on FOX 8 in July 2013, he has alternated wins and losses.

Guimaraes was set to make his UFC debut at the event. He is currently riding a seven-fight unbeaten streak and has finished nine of his 11 career victories.

With the change, the UFC Fight Night 83 lineup includes:

MAIN CARD (FOX Sports 1, 9 p.m. ET)

Donald Cerrone vs. Alex Oliveira

Derek Brunson vs. Roan Carneiro
