Fil-German Manny Ott returns from a long absence while his younger brother Mike makes his debut for the Philippine Azkals when they face Hong Kong in a friendly match on June 4.
The brothers are part of the 18-man roster that will see action in the former British colony.
Also in the cast are UFL standouts Phil Younghusband and Chieffy Caligdong and overseas based players Neil Etheridge, Rob Gier, Javier Patino and Stephan Schrock.
Tuesday match was supposed to be the first of a planned three-match friendly but the Azkals and the Philippine Football Federation have yet to fill up the two remaining dates following the scrapping of a June 8 match with Kyrgyzstan in Bishkek.
A possible dilemma may occur on June 4 as a key United Football League match between Global FC and the Loyola Meralco Sparks will be held at the same time as the Azkals friendly.
Five Global players - Jeff Christiaens, Jason de Jong, Marwin Angeles, Ed Sacapano and Carli de Murga - are part of the Hong Kong friendly while Loyola has Phil and James Younghusband.
However, both clubs and the UFL are currently working on a solution.
The older Ott, 21, last saw action two years ago when he played for the national U-23 side in the 2011 Southeast Asian Games in Jakarta. He scored the opening goal in a match against Vietnam but lost 3-1.
