Former Black Caps captain Brendon McCullum has doubts about the future of Test cricket.
McCullum told Cricket Monthly that he firmly believed Test cricket would not be around in time, because there were only so many teams that could afford to play it.
McCullum, who played 101 Tests, 260 ODI's and 71 T20 internationals for New Zealand, now plays T20 leagues around the world.
The 36-year-old said he loved Test cricket, but had concerns about its future.
"I'm also a realist that people are turning up and watching T20 not just at games but also on TV - society's changing, isn't it? People don't have four or five days to commit to Test cricket," McCullum said.
They might watch the first session, and the last session on day five if it's tight, but they're not going to then you strip it back a level as well and you think domestically, how can teams around the world afford to even exist?"
"Long long-term, I see a T20 franchise as owning players, and I don't see them releasing those players to play for their nation in a Test match," he said.
McCullum is currently in India, playing for Royal Challengers Bangalore, and he is one of only four players (Dwayne Bravo, AB de Villiers and Shane Watson are the others) who have appeared in all 11 seasons of the IPL.
