David Warner has issued a desperate plea for the return of his baggy green, which he believes may have been stolen, on the eve of his final Test.

Warner took to Instagram on Tuesday to say his backpack, containing two baggy green caps, had gone missing in transit between Melbourne and Sydney this week.

The bag is understood to have contained the cap Warner has worn for most of his Test career, as well as another.

“Unfortunately somebody has taken my backpack out of my luggage, which had my backpack and my girls’ presents in there,” Warner said ahead of the SCG Test against Pakistan.

“Inside this backpack was my baggy green. 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 greens.”

If Warner is unable to locate the cap before Wednesday’s third Test against Pakistan at the SCG, Cricket Australia will give him a replacement.

But it would be a hollow feeling wearing it given this is the last of Warner’s 112 Tests for Australia.

Warner said he had spoken with Qantas about the loss.

“A couple of days ago our bags got freighted via Qantas. We’ve gone through CCTV footage, they’ve got some blind spots apparently,” Warner said.

“We’ve spoken to the Quay West hotel, who we absolutely trust. They’ve gone through their cameras and no one has gone into our rooms.

“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 you.

“I would be grateful if these were returned ASAP.”

A Qantas Freight spokesperson said it was helping Warner try to find his bag, which had passed between several companies between hotels in Melbourne and Sydney.

“Our freight teams are continuing to search the terminals in Melbourne and Sydney and reviewing CCTV to try and locate the missing bag,” they said.

“We appreciate the importance of this bag and we’re doing everything we can to help find it.”

Warner has previously lost his baggy green ahead of a Test tour of Bangladesh in 2017. That time it was later found at home by his wife Candice.

He was issued a replacement cap for the first Test in Dhaka, where the opener hit his maiden Test century in Asia.

“I think there should be a countrywide search right now from the Australian government,” Pakistan captain Saad Masood said on Tuesday.

“We might need the best of detectives to get that back.

“Because he’s been a great ambassador and he deserves every bit of respect and every bit of celebration for his unbelievable career.

“He’s an example to openers. And just personally I love watching him bat and love watching him play.”
