The on-loan Cardiff centre-back, 22, fell to the ground head first after an aerial challenge during the goalless draw with Oxford and was taken to hospital as a precaution.
But scans have shown no lasting damage to Oshilaja’s neck, although he is a doubt for Tuesday night’s trip to Plymouth.
Dons doss Neal Ardley told the club’s official website: “Deji is a little bit stiff and mentally he has got to feel comfortable enough to play.
“Scans showed everything was fine with his neck and his spine. However, he has some tenderness in and around the back of his head and neck.
“Deji is one of those players who is athletic and agile in his style of play. If he feels it will affect him and he cannot do a job for the team in a tough game then he will let us know.”
