Due to the NCAA's new rule, a player can play in up to 4 games and still receive a redshirt designation.
13 of Miami’s 23 true freshman had previously played in 5 games and have burned their redshirt this season. They are: Hightower, Wiggins, Jordan, Mallory, Scaife, Ivey, Blades, Baxa, Lingard, Silvera, Pope, Davis, and Hall.
Of the rest, Marquez Ezzard, Patrick Joyner, and John Campbell played against Pitt.
Here's a chart to keep track of how many games the UM freshmen still eligible for a redshirt have participated in so far in 2018 (data is from UM's own official participation charts).

The rule does not only apply to true freshmen, though. Here are the non-freshman UM players that have yet to redshirt in their career and have played in 4 or less games this season, making them technically still eligible to redshirt this year.
From last week, both Corey Gaynor and Kai-Leon Herbert played against Pitt.
