New head coach Graham Potter could be without four players for the start of Albion’s pre-season programme.

Jose Izquierdo and Yves Bissouma have already been ruled out of the beginning of the Premier League campaign in August by injuries.

They could be joined on the sidelines by Gaetan Bong and Leon Balogun, due to their involvement in the Africa Cup of Nations with Cameroon and Nigeria.

The tournament gets underway in Egypt on June 21.

The round of the last 16 begins on July 5, just 48 hours before Potter’s squad fly out to Austria for a week-long training camp culminating in their opening pre-season friendly.

Bong and Balogun could miss other warm-up matches, depending on how far their countries progress and whether Potter grants them extra time off.

The Africa Cup of Nations quarter-finals are on July 10 and 11, semi-finals July 14 and final July 19 - the same night that Albion go to Crawley Town.

The Argus has previously revealed the injury issues for Izquierdo and Bissouma.

Colombian winger Izquierdo has undergone more knee surgery. Bissouma was withdrawn by Albion from Mali’s Africa Cup of Nations squad because of a long-standing shoulder problem which also required an operation.

Percy Tau is in the tournament as well.

Albion’s South African star will be loaned out again this season due to work permit obstacles.

Tau spent last season on loan to Union Saint-Gilloise, the Belgian second tier club of Albion owner-chairman Tony Bloom.
