As an amateur, he represented Gambia at the 2008 Olympics, reaching the first round of the middleweight bracket.
Jack was raised in Stockholm, where he was influenced by both Swedish culture and his Gambian heritage. He developed an interest in various athletic activities during his childhood, participating in several sports. However, boxing became his main focus.
Jack began his amateur boxing career in 2001 at the age of 18. He held a record of 150 wins and 25 losses. He won Sweden's national championship five years in a row, 2004–2008, 4 times at middleweight and once at light heavyweight. Jack boxed for Djurgårdens IF. In 2007, Jack was named the boxer of the year by the Swedish Boxing Federation. In his last national championship in 2008 he defeated fellow rising star Erik Skoglund in the finals. He represented Sweden at light-heavyweight before changing to Gambia, where he qualified for the 2008 Games. At the 2nd AIBA African 2008 Olympic Qualifying Tournament he breezed through the competition to win; the final was a shutout win over DR Congo's Herry Saliku Biembe. Jack qualified for the 2008 Olympics for Gambia in the middleweight division, and was the nation's flag bearer at the Opening Ceremonies. He lost in the first round to India's Vijender Singh.
Jack started his professional career in his native Sweden where he won his debut fight by unanimous decision on 6 June 2009. His next four fights were contested in Sweden and Finland, with Jack winning each by KO/TKO, two in the first round.
In 2009, Jack met former heavyweight champion Shannon Briggs at a Swedish boxing event, held in honor of the Swedish boxing legend Ingemar Johansson, where Jack was fighting and Briggs was brought in as a guest. Jack would later move to the United States in 2010 to train with Briggs and eventually sign with Lou DiBella and the Warrior Boxing Promotions in 2011, bringing his 5–0 record over to the states. In 2011 and 2012 Jack would fight and win 6 times. 4 by TKO and 2 by decision. Including defeating Adam Collins by TKO on 16 December 2011 and a unanimous decision over 6 rounds (60–54, 59–55 and 58–56) over Grover Young on 7 March 2012. The biggest win came against fellow undefeated, 17–0, prospect Alexander Brand on 11 May 2012 by eight-round split decision 77–75, 77–75, and 75–77.
Following his success extending his record to 11–0, Jack was spotted by Floyd Mayweather in a sparring session in opposite Andre Dirrell. Mayweather was impressed and quickly signed Jack to Mayweather Promotions and to his team. On 2 February 2013 he defeated Jonel Tapia by knockout in the first round. Three weeks later he fought Don Mouton 23 February 2013 and won by unanimous decision (78–74 on all scorecards). On 4 May 2013 Jack took on Michael Gbenga and won by TKO from a body shot in round 3.

In his next fight he took on Rogelio Medina on 6 December 2013. He won the fight by TKO after scoring 3 knockdowns in round 6. On 28 February 2014 Jack fought Derek Edwards and lost for the first time after being stopped by TKO in the first round. Edwards knocked down Jack twice in first round after catching him with an overhand right counter. Prior to the loss, Jack had been in line for an elimination bout against James DeGale. The upset result was also a candidate for Upset of the Year in 2014. Jack got back into the win column on 30 August 2014 when he fought Jason Escalera at the Palms Casino and Resort, Pearl Theater in Las Vegas, Nevada, and won by unanimous decision 100–90, 100–90, and 99–91.
