The UFC is set to invade the Conseco Fieldhouse in Indianapolis, Indiana on Saturday, September 25.
There has been speculation about multiple fights already being added to UFC 119 and today a former title holder has been said to be joining the card.
Sherk last competed at UFC 98 where he lost via unanimous decision to the current 155 lb. title holder, Frankie Edgar.
The undefeated Dunham has gone 4-0 since entering the organization with his most recent win coming against Tyson Griffin at UFC 115.
Dunham and Sherk are projected to compete during the televised main card portion of the event.
