Wasserman Schultz is expected to gavel the convention in and out, but not speak in the wake of the controversy surrounding the leaked emails, a top Democrat said.
Fealk said he viewed the emergence of hacked DNC emails, which suggested favoritism of Clinton, as a revelation and evidence of the party's disrespect for progressives.
The decision follows an uproar over the almost 20,000 emails released by Wikileaks that revealed efforts were discussed by party staffers to seemingly undermine the candidacy of Sanders, the Vermont senator who was runner-up to Clinton in the Democratic presidential campaign.
On Saturday, after a lengthy debate during the Democratic Party's rules committee - as Occupy protesters marched outside - the Sanders and Clinton delegates agreed to create a "unity" commission. This election saw significantly fewer debates, and the debates that did take place aired at off-hours.
While party chairwoman Debbie Wasserman Schultz is stepping down soon, she will still have a convention role, which could draw jeers from Sanders delegates.
President Obama issued a statement on her resignation on Sunday, thanking Schultz for her service.
Following the resignation, Clinton released a statement in which she said she's named Schultz an honorary chair of her campaign's 50-state program.
"I will make sure that Florida has a loud voice, to speak loud and proud on our values", Wasserman Schultz added.
In one leaked email, a DNC official wondered whether Sanders' religious beliefs could be used against him, questioning whether the candidate may be an atheist.
The Democrat familiar with the decision said it was done in hopes of preventing chaos on the convention floor among Sanders supporters.
"I always said that Debbie Wasserman Schultz was overrated".

DNC Chairwoman, Debbie Wasserman Schultz, D-Fla., greeted the Florida delegation at a breakfast, Monday, July 25, 2016, in Philadelphia, during the first day of the Democratic National Convention. It was there Wasserman Schultz earned her reputation as a workhorse and outspoken liberal willing to spar with Republicans on television.
Before cutting her speech short, she also discussed Sunday night's Fort Myers nightclub shootings, vowing to "continue to fight to make sure that people who should not have gun controls can not get access to them, and I will continue to fight every day with you to make sure that doesn't happen".
