Sriwijaya beat Muang Thong United 7-6 on penalties following a 2-2 draw after extra-time to keep alive the Indonesian side's hopes of reaching the group stage of the AFC Champions League.
Keith Gumbs opened the scoring after 48 minutes at Jaka Baring Stadium before Datsakorn Thonglao equalised with eight minutes remaining. Muang Thong then had Panupong Wongsa sent off but the Thais held on to take the game to extra-time.
Carlos Roberto Carvalho's side then took the lead in the 92nd minute when Teerasil Dangda lobbed the Sriwijaya goalkeeper but the hosts hit back as Thierry Gautessi headed home from Budi Sudarsono's cross. Neither side were able to find another goal, meaning penalties would be needed to determine a winner.
The first four spot-kicks were successfully converted before Sriwijaya twice had the chance to win the match after Dagno Siaka and Christian Kouakou missed their efforts. But Diano De Souza and Gautessi failed to convert their chances before Supardi Nasir netted the decisive effort to secure the victory for Sriwijaya.
The Indonesians will tackle Al Ain of the United Arab Emirates on 19 February with the victor of that game sealing their place in the group stage of the Asian Champions League.
In the West Zone play-off, Al Sadd clinched an impressive 5-1 victory over Syrians Al Ittihad at Sheik Jassim Bin Hamad Stadium in Doha. Ivory Coast striker Abdul Keita put the Qatari side ahead after 13 minutes and made it 2-0 16 minutes later.
The goals continued to come for the hosts with Leandro da Silva scoring in the 33rd minute, and the Brazilian completed his brace six minutes after the hour. Majdi Siddiq compounded Al Ittihad's woes with a fifth after 76 minute before Omar Hemidi managed to pull one back for the visitors nine minutes from time, though it was little consolation for the visitors.
Al Sadd will meet Indian side Dempo SC also on 19 February in a battle for a place to reach the tournament proper.
