Playing in front of its home fans at the Al Saada Sports Complex in Salalah, the Dhofar heavyweight was held to a goalless draw and needed a 4-3 shootout win to quell the spirited challenge from first-division side Seeb in a round-of-32 match.
A three-time champion, Seeb had last won the title in 1998 when it completed a hat-trick. Since then, it has failed to regain the lost glory and on Saturday, it was a typical story of being so near and yet so far.
In another late night game played on Saturday, Al Khabourah edged past Al Mussanah by a solitary goal at the Seeb Sports Stadium to complete the line-up of the 16 teams that booked their spots in the next stage.
The draw for the 16 teams will be held at the Oman Football Association (OFA) headquarters on Monday. The 16 teams that will go into a draw are Sohar, Al Hamra, Jalan, Muscat, Al Salam, Saham, Al Nahda, Al Mudhaibi, Nizwa, Fanja, Bausher, Oman, Dhofar, Al Khabourah, Al Suwaiq and Al Shabab.
