“Hi all, this is my last resort, but my backpack, which contained my Baggy Green, has been taken from my luggage, which was transported to Melbourne airport and flown on Qantas to Sydney a few days ago,” he said in an Instagram post along with a video on Monday.

The left-handed batter would sign off from the Test cricket in the match against Pakistan that would begin on Wednesday (tomorrow).

Warner, 37, has plundered 8,695 runs at an average of 44.58, with 26 centuries and 36 half-centuries.

“It’s sentimental to me. It’s something I’d love to have in my hands walking out there this week. If it’s the backpack you really wanted, I have a spare one here. You won’t get into trouble. Please reach out to Cricket Australia or myself via my social media. I’m happy to give this to you if you return my Baggy Green.”

According to Warner, Qantas Airlines has said that they checked their cameras and have not seen anyone open their bags and take the backpack, however, they do have blind spots.

“If you are the person, who was either working for the company driving it to and from the airport or working for Qantas and have, by chance, just wanted the backpack, I have one for. I would be grateful if this were returned asap. Thanks,” he said.

Meanwhile, Pakistan’s Test skipper Shan Masood called for a country-wide search to get the cap back.

“Warner’s been a great ambassador, he deserves every bit of respect, every bit of celebration for his unbelievable career. I hope they find his cap. It’s the most precious thing for any cricketer & I hope he gets it back.”
