Multiple sources have confirmed that Diego Sanchez is out of his fight at UFC 90 against Thiago Alves.

Sanchez pulled out of the fight due to torn rib cartilage and will be replaced on the Oct. 25 fight card at the Allstate Arena by fellow TUF 1 alum Josh Koscheck.

Koshcheck had been scheduled to headline UFC Fight Night 16: “UFC Fight for the Troops” on Dec. 10 in Fayetteville, N.C. against Yoshiyuki Yoshida. A replacement for Koscheck in that bout is still pending.
