Sitkowski had entered the portal on Nov. 25, allowing for the potential to transfer and for other programs to contact him, but he is now no longer in the system.
Sitkowski threw for 1,158 yards in his freshman season in 2018, with four touchdowns and 18 interceptions. He lost the starting job to transfer McClane Carter to start the 2019 season, but Carter eventually suffered a concussion and was replaced by Sitkowski.
The sophomore threw for 304 yards and one touchdown against Boston College and 106 yards against Michigan. Head coach Chris Ash was then fired after the Michigan game, and Sitkowski decided to take advantage of the redshirt rule allowing him to play in up to four contests without burning his redshirt.
He did not participate in any other games this season, so if he decides to remain at Rutgers, he will have three years of eligibility left.
