Correct me if my interpretation of this newly released Fox News standard is not correct, but it looks like only six candidates will be included in the main stage debate the rest dropping to the second-tier.

At current polling standards, these qualifiers would put: Trump, Cruz, Rubio, Carson, Bush and Christie on the main event stage.

(Via FNB) The debates will factor in both national polls, as well as those based in Iowa and New Hampshire conducted and released prior to Monday, January 11 at 6 p.m./ET. The primetime debate will feature candidates that place in the top six nationally, and place within the top five in Iowa or New Hampshire, while the remaining candidates will be invited to the early debate.

In order to qualify for the primetime debate, candidates must either:

• Place in the top six nationally, based on an average of the five most recent national polls recognized by FOX News.
OR
• Place in the top five in Iowa, based on an average of the five most recent Iowa state polls recognized by FOX News.
OR
• Place in the top five in New Hampshire, based on an average of the five most recent New Hampshire state polls recognized by FOX News.

Such polling must be conducted by major nationally and state recognized organizations that use standard methodological techniques (i.e., live interviewers, random digit-dial sampling techniques and include both landlines and cell phones). In order to qualify for the first debate, candidates must register at least one percent in ONE of the five most recent national polls. (read more)

If accurate interpretation the “under-card debate” would be: Carly Fiorina, Rand Paul, John Kasich, Rick Santorum, Mike Huckabee, George Pataki and maybe Jim Gilmore (if he surges).
