Although the fight was originally agreed to contest both of Gamboa's WBA and IBF featherweight titles, Gamboa missed a mandatory re-weighing procedure established by the IBF which resulted in the title being withdrawn. The fight lasted only four rounds after Gamboa sent Solis to the floor a total of five times, causing referee David Fields to stop the fight, giving Gamboa the victory by TKO. After the fight, Gamboa was interviewed, a moment that Gamboa took advantage of to express his awareness and support towards the victims of Japan's latest earthquake and tsunami. Gamboa also took the opportunity to proclaim his desire to fight higher caliber featherweight boxers such as Indonesian Chris John and Puerto Rican Juan Manuel López, who was attending the fight as a spectator and decided to come up to the ring and proclaim his desire for a possible fight with Gamboa as he also made the observation that it was a business decision to be taken by their shared promoter Bob Arum.

On 10 September 2011, Gamboa fought Ring top 10 ranked featherweight Daniel Ponce de León in a non-title fight. Gamboa managed to connect more punches in every round to keep the scorecards in his favor. Although there were not many exchanges, Gamboa's hand speed and reflexes were on display as he connected with quick and short combinations and managed to avoid some of de León's left swings with his characteristic upper body movement. In the eighth round, during a short exchange, Gamboa and de León accidentally clashed heads, resulting in de León suffering a cut to his forehead, consequently the referee stopped the fight and asked de León's corner to check the boxer's wound.

In July 2012, Gamboa signed a promotional contract with 50 Cent and Floyd Mayweather's promotional company, The Money Team Promotions.

Gamboa then landed a fight on the undercard of Manny Pacquiao vs. Juan Manuel Márquez IV on 8 December 2012. He fought Michael Farenas, who fought to a draw in his previous fight with WBA title holder Takashi Uchiyama. Gamboa was show boating throughout the fight while Farenas maintained his focus. Farenas was dropped twice which gave Gamboa more confidence, dropping his hands occasionally. In the ninth round Gamboa tried to finish Farenas off with a barrage of punches but Farenas countered him with a left hook that dropped Gamboa. Gamboa stopped show boating after the ninth round, winning the fight by unanimous decision.[17]
