Shane Warne suffered a fracture in his arm after being hit by Brett Lee's beamer.
According to the BBC, the accident was unintentional and happened during a Lord's bicentenary celebration match on Saturday.
The match was organized to celebrate 200 years of cricket at the current Lord's stadium. The first Lord's ground was founded by businessman Thomas Lord in 1787. The current ground is the third in line to take up the English businessman's name.
The fracture will prevent the 44-year old former Australian bowler from playing in the second innings, the report added.
