Albion duo Semi Ajayi and Grady Diangana both competed in 2026 FIFA World Cup qualifiers on Sunday afternoon.
Ajayi, who scored his first international goal on Thursday against Lesotho, played the entirety of Nigeria's 1-1 draw away to Zimbabwe - a contest which was hosted in Butare, Rwanda.
Walter Musona put Zimbabwe ahead in the first-half, but the Super Eagles hit back in the second period courtesy of Kelechi Iheanacho to earn a draw.
The result leaves Semi's side on two points from their opening two group games following successive 1-1 scorelines.
Elsewhere in Africa, Diangana was handed a start for DR Congo in their away fixture against Sudan.
The Baggies winger completed 45 minutes at the Martyrs of February Stadium in Libya and was replaced by Gael Kakuta.
Sudan won it 1-0 thanks to Charles Pickles' own goal just 11 minutes from the end.
Diangana's nation have collected three points from their opening two Group B encounters.
Ajayi and Diangana will now report back to Albion ahead of Saturday's Sky Bet Championship clash with Ipswich Town at The Hawthorns (ko 5.30pm).
