CNN will conduct a live drawing in order to determine the lineup for each of the two-part debates scheduled to take place this month.
The debate, which is scheduled for July 30 and 31, will have 10 candidates on the stage each night, and the live drawing will be conducted nearly two weeks earlier, on July 18, the network announced Monday.
Dana Bash, Don Lemon, and Jake Tapper will moderate the debate.
At this point, 19 of the 20 total participants from the first debate will be on the stage for the second one. California Rep. Eric Swalwell, who dropped out Monday afternoon, will likely be replaced with Montana Gov. Steve Bullock, who would have gotten the final spot over Swalwell as a result of the tiebreaker anyway.
MSNBC, NBC, and Telemundo aired the first debate last month.
