Top quarterback prospects Jameis Winston and Marcus Mariota will throw at the NFL combine, according to reports.

ESPN's Chris Mortensen reports Mariota will throw on Sunday, while Ian Rapoport of the NFL Network reports Winston plans to throw, too.

Mariota had said Monday that he was unsure whether he would throw for scouts at the combine as he continues to recover from a shoulder injury. Winston's quarterbacks tutor, George Whitfield Jr., also said Monday he was not sure Winston would throw.
