The Belgian rider from Omega Pharma-Quick Step fell on a downhill stretch before the final climb of stage five on Monday.
He sustained the injury to his left elbow after it struck the asphalt.
However, Serry finished the stage before being immediately taken to the nearby hospital to undergo X-rays, which showed that there were no fractures.
In agreement with the team’s medical staff, Serry will decide on Tuesday whether or not to line up for the start of stage six.
Meanwhile, Matteo Trentin had surgery on Sunday at the Herentals Clinic in Belgium for a fracture to the scaphoid of his right hand — the result of a fall in the Omloop Het Nieuwsblad on Saturday.
Due to the complexity of the fracture, Trentin will be out of action for four weeks, after which he can gradually return to training.
