The 6-foot-4, 230-pound Marini received his first offer from Louisville earlier in the month and recently added a second offer from Florida International.
Marini was primarily used as a blocker his junior year at Lake Mary but did have a touchdown reception.
Fernandez, a 6-1, 200-pound junior, received an offer from NC State last week. He had 91 tackles and two forced fumbles during his junior season. Fernandez also attended Miami's junior day earlier this month.
Both players have been invited to go to UCF's spring game in April.
