Mertz started 11 games this season for the Gators after transferring from Wisconsin, throwing for 2,903 yards with 20 touchdowns and three interceptions while completing 72.9% of his passes. He missed the season finale against Florida State after injuring his collarbone the previous week in a loss to Missouri.
His return gives the Gators a veteran presence in the quarterback room, with the addition of freshman five-star quarterback D.J. Lagway expected on national signing day, Dec. 20. Lagway, the No. 16-ranked prospect in the 2024 ESPN 300, has been committed to Florida since last December.
