However, the five-time Saudi champions will be missing suspended Saudi Arabia midfielder Ahmed Ateef, Abdoh's older brother and international teammate.
Al Hilal, Shabab's Riyadh neighbours, will host Zobahan at the King Fahd International Stadium, where Eric Gerets' side have attracted crowds of over 50,000 in the round of 16 and the quarter-finals.
The two-time Asian Club Championship winners also need to win at home after the first leg was decided by a second-half free-kick by Zobahan captain Ghasem Hadadifar.
Hilal were awarded a penalty in the first half but Sweden winger Christian Wilhelmsson had his effort saved by Shahab Gordan, while Nawaf Al Abid hit the post with a long-range shot in the 70th minute.
Al Abid is an injury doubt for Wednesday, defender Hassan Khairat could again be absent, while central midfielder Khaled Aziz is out until January.
However, Hilal could welcome back both Brazilian playmaker Thiago Neves, who missed the first leg through injury, and central midfielder Mirel Radoi, who was away with Romania for their UEFA 2012 qualifier against France.
Zobahan arrived in Riyadh on Saturday after beating Malavan 3-0 on Friday with early goals from right-back Mohammad Hosseini – the club's top scorer in the league with six goals – and attackers Jalal Rafkhaei and Esmaeil Farhadi.
The ‘Greens' lead the Iran Pro League after 11 games, following runner-up finishes for the last two seasons, and are now bidding to emulate fellow Esfahan club Sepahan, who reached the AFC Champions League final three years ago.
Zobahan, Hilal and Shabab are all competing in the semi-finals for the first time since the AFC Champions League was inaugurated in 2002.
Seongnam reached the semis three years ago and the final in 2004, when they lost to Jeddah giants Al Ittihad over two legs. Ilhwa won the former Asian Club Championship in 1995, beating Al Nassr of Saudi Arabia.
Hilal, Saudi Arabia's most successful club with 12 league titles, won the Asian Club Championship in 1991 and 2000 and also the Asian Cup Winners' Cup twice, in 1997 and 2002.
