Iowa linebacker Dillon Doyle announced his decision to enter the transfer portal Tuesday:
As Adam Rittenberg of ESPN noted, the player is the son of Hawkeyes strength and conditioning coach Chris Doyle.
The older Doyle has been with the program for 21 years but was placed on administrative leave Saturday after allegations of racial discrimination from several former players.
The 51-year-old, who is the highest-paid strength coach in the country, denied the accusations.
"I am confident that a complete review of the body of work over 21 years will speak for itself and I am trusting the process to respect the rights and experiences of all parties involved," he said in a statement, per Rittenberg.
