Bin Hammam has represented Asia on FIFA's executive committee since 1996. He was elected AFC president in 2002, and was serving his final four-year mandate when the FIFA election scandal broke.
United Arab Emirates Football Association President Yousuf al-Sarkal called for the AFC to reinstate its leader.
"This is to be fair to the man," al-Sarkal, who is a member of the AFC's executive board, told The Associated Press. "He has gone through enough of allegations and accusations. It's not fair for an individual who has served football in the right way."
Bin Hammam had once been Blatter's close ally and worked as a campaign manager for his previous FIFA election victories in 1998 and 2002.
However, the Qatari official expressed growing frustration in claiming that the now 76-year-old Swiss reneged on promises to step down.
