The 42-year-old would be permitted to represent his country in the visually-impaired football tournament as keepers within the squads are able-bodied athletes.
"A goalkeeper is not subject to rules that he must have some disability and no rules when it comes to career," the Daily Star quotes President of the Disabled Sports Association Friedhelm Beucher as saying.
"Jens Lehmann and Oliver Kahn or any other retired goalkeepers are practically available. We will now discuss this internally."
When asked about a possible inclusion in the Paralympics team, Lehmann said: "It's very interesting, if I am fit to go there."
Lehmann retired from the game last year.
