Lionel Messi may have the chance to take over the Inter Miami captaincy, with their usual skipper ruled out with a long-term injury.
Gregore has been sidelined since March and is not expected to return to fitness until the end of September. Standing in for the midfielder has been Tottenham flop DeAndre Yedlin, but Miami have won just three games with the American as skipper.
Yedlin joined Spurs in 2014, but made just one appearance before leaving White Hart Lane two years later. He then spent five years with Newcastle, before returning to his homeland last February and assuming the captaincy after Gregore's injury.
