Al Khor will take on holders Lekhwiya in the Emir’s Cup quarterfinal at the Al Sadd Stadium on Thursday.
In a third-round match last week, Khor pipped Al Sailiya 4-3 in shoot-out after regulation time ended 2-2.
Al Gharafa, Al Kharaitiyat and Umm Salal also progressed to the last eight.
Gharafa defeated Mesaimeer 2-0 to set up a clash with Rayyan. Kharaitiyat, who had an impressive run in the league’s second phase, continued their good work to beat Al Ahli 4-2 on penalities after regulation time ended 3-3. Amhed Ajlani’s men will next take on newly-crowned Qatar Cup champions Al Sadd on Friday.
Umm Salal, who have turned in a series of convincing performances since Egyptian coach Mahmoud Jaber took charge midway through the season, defeated Al Shahaniya 2-1. They will meet last year’s runners-up El Jaish.
