Colton (Calif.) athlete Jonathan Mack picked up his third offer, and second from the Big 12, last week.
"Jonathan was offered by Iowa State," said Colton recruiting coordinator, B.J. Bray.
The Cyclones join Nebraska and UNLV in offering Mack.
The 5-10, 175-pound Mack, is the younger brother Christian Ramirez, listed #1 at running back at UCLA.
As a junior, Mack had 42 tackles and three picks for the Yellowjackets.
