Ghana striker Emmanuel Banahene is set for a lengthy spell on the sidelines after tearing a cruciate ligament on Saturday during a league match in Egypt.
Ismaily coach Terek Yehia announced his goal poacher picked up the injury as they suffered a 3-0 defeat against ENPPI.
He becomes the fourth Ismaily player to suffer a ligament injury this season after Hosni Abd Rabbo, Mahmoud Metwally and Mahmoud Aziz.
In the match, Banahene nearly scored when he found himself one-on-one with goalkeeper Abdel-Monsef but his effort hit the post.
