The twin loss added to the misery of Saudi Arabia, which saw three teams lose in the round of 16.

The other loss was incurred by  Al-Hilal, which was eliminated by fellow Saudi team Al-Ittihad via a 3-1 victory in Jeddah on Tuesday.

A brace from striker Igor Castro helped Zobahan eke out a 4-1 victory over Al Nassr in their game in Isfahan, Iran on Wednesday.

Zobahad midfielder Mohammad Qazi opened the scoring in the first minute, and Castro followed it up with a close-range strike just five minutes later.

Castro scored again in the 63rd to make it 3-0 before Al Nassr pulled a goal back through Badr Al-Motava in the 67th. But eight minutes later, midfielder Shahin Kheiri sealed the win with a long-range goal and make Zobahan the second Iranian side in the quarters along with Foolad Sepahan.

In the other game played in Dubai, Al Shabab's Abdulla Koni headed home their lone goal in the 12th minute and the home side held on for the victory in searing heat that forced organizers to turn on the Al Sadd stadium cooling system.

Al Shabab had several chances to equalize but were repeatedly thwarted by Al Sadd goalkeeper Mohamed Saqr. In the 13th minute, Al Shabab’s Marcelo Camacho produced a spectacular shot that forced Saqr to make a diving save.

Camacho was on target again in the 25th but Saqr punched the ball clear.
