Michael Owen will keep the captain's armband at Newcastle United.
Shay Given had captained the side in the FA Cup last week, and Alan Smith before that under Sam Allardyce.
"I think we'll leave it with him at the moment, and if he comes to me and says he enjoys it, then we can look at it longer term," said Keegan, who handed the armband to Owen as an olive branch after the striker had criticised his spell as England manager in his autobiography.
