The last time anyone saw former world champion Amir Khan (31-4, 19 KOs) in the ring, he was knocked out cold by Canelo Alvarez (49-1-2, 34 KOs) in May of 2016 at the T-Mobile Arena in Las Vegas.
Khan had moved up to a catch-weight of 155-pounds to challenge Canelo for the WBC middleweight title.
After nearly two years of inactivity, Khan is scheduled to return to the ring on April 21 when he faces Phil Lo Greco at the Echo Arena in Liverpool.
Khan admits that during his time in the jungle for the I'm A Celebrity... Get Me Out of Here reality show in Australia, he questioned his boxing future.
Earlier this year, Khan made a shocking move when he signed a three fight deal with promoter Eddie Hearn.
Khan and Hearn have verbally been feuding for quite some time - and the Bolton boxer went as far as to threaten rival Kell Brook to dump Hearn in order to get a deal done.
To show he was serious about his comeback, he signed with Hearn and plans to fight three times this year.
"There were times in the jungle when I thought about where I want to be in boxing. Do I still want to fight? Do I still want to box? I could retire tomorrow and say I have had a great career, won world titles, and have had a great time. But there was still a little bit more left I wanted to achieve from boxing," Khan said to Sky Sports.
"While I was in that jungle I thought, look, I have just turned 31, I am at the peak of my career now, and this next year or two are going to be the final chapter.
"So, I want to make sure that I grab it with both hands and win another world title, win more fights, and call it a day on top. I can't just retire after the Canelo loss. Having had that defeat, I want to see how I am as a fighter. Coming back into boxing - let's see how this fight goes and take it from there."
