A major Davis Cup revamp that would condense the annual global tournament into an 18-team, week-long event will be voted upon Thursday with major tennis leaders divided over the proposal.

The International Tennis Federation annual meeting in Orlando will see about 120 delegates decide the fate of the 118-year-old men's team competition with two-thirds majority support needed to approve the measure, which is backed by federation president David Haggerty.

Kosmos, a group led and founded by Barcelona football star Gerard Pique and backed by Japanese billionaire Hiroshi Mikitani, has vowed $3 billion over 25 years to support the new event.
