At the start of 2017, Cummings was named to the 2017 Copa Centroamericana Best XI for his performances in the January tournament, which qualified Panama for the 2017 CONCACAF Gold Cup. In February, he received a call-up for Panama's 2018 FIFA World Cup qualification matches against Trinidad and Tobago and the United States on 24 and 28 March, respectively, but was called home from camp by San Jose due to injury issues that the club did not wish to aggravate. These injuries persisted throughout the year and prevented him from taking part in the Gold Cup and in Panama's September World Cup qualifiers as well.
