Policeman Samuel Sarfo makes Black Stars debut
The 26-year-old came on for fellow central defender Jerry Akaminko in the 81st minute in East Hartford, Connecticut.
For the last nine minutes he spent on the pitch, Sarfo showed great composure at the back as he tried to prevent the USA centre-forwards from scoring.
The centre-back was one of the policemen deployed to provide security for the Black Stars during the Afcon qualifier against Rwanda in 2016.
Sarfo has scored six goals and provided two assists for Liberty in their bid to avoid relegation.
