Andrew Holbrook will make his Octagon debut against Ramsey Nijem at UFC on Fox 16.
Holbrook replaces Erik Koch, who had to withdraw from the lightweight bout due to injury. Promotion officials recently announced the change. UFC on Fox 16 takes place United Center in Chicago and is headlined by a bantamweight title rematch between T.J. Dillashaw and Renan Barao.
A native of Indianapolis, Holbrook is unbeaten in nine professional outings, with all of his triumphs coming by way of submission.
