Amir Khan will fight Manny Pacquiao on April 23 in a “super fight” both men announced on Twitter.
They revealed last week that negotiations were ongoing, though no venue has been confirmed.
Former world light-welterweight champion Khan, 30, posted: “My team an I have agreed terms with Manny Pacquiao and his team for a super fight #pacquiaokhan #April23rd.”
Manchester and Khan’s native Bolton have both been suggested as possible locations as has the United Arab Emirates.
The Filipino Pacquiao, 38, won back the WBO world welterweight title in November, while Khan’s last bout was a defeat to Mexican Canelo Alvarez last May in Nevada, USA.
Pacquiao continues to be trained by Freddie Roach but Khan left the American in 2012 and is now under the tutelage of Virgil Hunter.
