Chappell, a former Australian Test captain, stepped down as India's coach after the team was knocked out of the Cricket World Cup in the first round. According to Indian news reports, he became unwell on Friday after meeting India's cricket administrators to discuss the team's poor world cup showing.

Various reports described him as suffering either dehydration, an anxiety attack or simply feeling unwell.

Chappell visited the Bombay Hospital for a "routine executive check-up", a hospital spokesman said. He underwent tests on his kidneys, liver and blood. "There is presently no cause for concern." Doctors would examine the results and decide if Chappell can fly out of Mumbai.
