Riding the highest point of his international career, Taylor's career came to a sad and sudden end when he was forced to retire in April 2016 at the age of just 26.

Having played two Tests for Australia in 1997, paceman Cook retired from the game in 2004 at the age of 32 due to a string of serious injuries.

Coupled with two broken ankles and an ongoing back problem towards the end of his career, he was forced into an early exit.
A left-arm wrist-spinner who played one Test for Australia in 2008, Casson was forced to retire at the age of 28 due to the effects of a long-term heart condition. Having had heart surgery as a child, Casson had successfully managed the ongoing condition throughout his career and ascended to the Test side when he made his international debut against the West Indies in Babados. But after doctors warned the spinner that his life could be at risk if he continued playing, he called time on his career in 2011.
Player of the final at the 2010 World T20, Kieswetter looked destined for big things after leading England to their first-ever global trophy.

His initial attempts to return from injury were hampered by ongoing vision issues and, having accepted that he would be unable to return to his absolute best, he decided to call it quits. Kieswetter has since tried his hand at another sport, recently starting a new life as professional golfer.
