It should be possible to obtain any Personal Data from the owner of the image (who may or may not be the photographer), but a photograph of a sporting event may or may not be considered Personal Data as defined by 2016/679 (GDPR), depending on the purpose of its processing.
The UK Information Commissioner's Office (ICO) provides the following on page 15 of their interpretation :
At New Year celebrations in Trafalgar Square two almost identical
photographs of the revellers are taken by two separate photographers
and stored in electronic form on computer. The first photographer, a
photo journalist, takes a picture of the crowd scene to add to his
photo library. The second photographer is a police officer taking
photos of the crowd scene to identify potential troublemakers. The
data in the electronic image taken by the journalist is unlikely to
contain personal data about individuals in the crowd as it is not
being processed to learn anything about an identifiable individual.
However, the photo taken by the police officer may well contain
personal data about individuals as the photo is taken for the purpose
of recording the actions of individuals who the police would seek to
identify, if there is any trouble, so they can take action against
The people sharing or selling the photograph, and the owners of the medium on which they are shared, could have obligations that the photographer does not.
