Ohio Gov. John Kasich and New Jersey Gov. Chris Christie will take the stage Thursday -- leaving behind Texas Gov. Rick Perry, relegated to the 5:00 p.m. debate for those who didn't make the top tier.

Kasich and Christie grabbed the last two spots for the GOP debate, Fox News announced Tuesday evening. The two will go head-to-head with real estate mogul Donald Trump; former Florida Gov. Jeb Bush; Wisconsin Gov. Scott Walker; retired neurosurgeon Ben Carson; former Arkansas Gov. Mike Huckabee; Texas Sen. Ted Cruz; Florida Sen. Marco Rubio; and Kentucky Sen. Rand Paul.

The 10-candidate roster was based on five recent national polls of Fox News' choosing. Only 10 of the 17 Republican candidates were chosen.

The debate will air 9 p.m. EST Thursday in Cleveland and will be broadcast by Fox.
