After a 6-month lay off, Yafai returned to the boxing ring in March 2015, beating Polish boxer Krzysztof Rogowski at the Ice Arena in Hull via 3rd-round TKO.

Two months later, Yafai fought at the Barclaycard Arena in Birmingham beating Spanish boxer Arnoldo Solano (14–7, 0 KOs) via points decision.

In August, Yafai defeated Spanish boxer Angel Lorente at the Craven Park Stadium in Hull via a 6-round points decision, after knocking him down once in round 5.

Yafai started off sharp and cut Wale over the right eye in the round 1, although a replay showed that it was due to a clash of heads.
