Evans returned after a 14-month layoff to defeat Ortiz in a dominant victory that earned him a shot at the UFC light-heavyweight title.
"[My thumb is] pretty good," Evans said following the UFC-on-FOX press conference earlier this week. "I just got three pins into the thumb. The thumb is completely broken; it's shattered."
The injury came just moments into the fight when Evans was trying to finish Ortiz. Evans, however, underwent an operation to repair the damage and assured everyone he will begin training in the next few weeks.
"They put some pins in it to hold it together for a few weeks," said Evans. "I have got like four more weeks of this, and then I am good to train again."
Evans will now await the winner between Jon Jones and Quinton "Rampage" Jackson at UFC 135.
