Australia are wearing black armbands during the first Test against Pakistan at the Gabba.
They are wearing the armbands as a tribute to former Australian Test cricketer Tony Mann.
Mann played four Tests for Australia across 1977 and 1978.
The Western Australian all-rounder passed away at the age of 74 on November 15 after a long battle with cancer.

Mann became famous for becoming just the second nightwatchman to ever make a century in Test cricket.
He scored 105 against India in Perth in December 1977 to help lead Australia to a famous victory.
Australia were chasing 339 for victory in the fourth innings and chased it down with two wickets to spare.
It remains Australia's fourth-highest successful fourth-innings chase in Test cricket history.
Mann took four wickets across his four Test matches, including best innings figures of 3/12.
He also took plenty of wickets for Western Australia, sitting 11th on their list of all-time first-class wicket takers.
He took 196 wickets for WA at an average of 33.63 and best figures of 6/94.
Today our Aussie players are wearing black armbands in memory of former Australian Test cricketer Tony Mann, who sadly lost his battle with cancer last week. Tony was an outstanding member of the Western Australian cricket community and a true friend of cricket. pic.twitter.com/GqurTkkVCg
