Striker gets first journey with senior side.
It was recently revealed that Nnamdi has been offered a professional development contract for next season by boss Joe Dunne and he will be around the senior squad for the first time for the game at Gigg Lane.
Boss Joe Dunne has a first team squad that has been affected by a sickness bug during the course of this week and will have some late decisions to make for his side at the weekend.
As a result, Nnamdi has been joined by a number of the other young pros in the first team squad as Joe ensures he is good to go for the big game against the Shakers.
Meanwhile, the U's will know that key striker Jabo Ibehre will be back for the game against MK Dons next Saturday as he completes his suspension for the sending off against Hartlepool.
Safe trip to all U's fans who are making the journey up.
