Running back Eric Graham and linebacker Justin Jinning became the first two football players in Iowa's recruiting Class of 2015 to leave the program.

Jinning, a native of The Colony, Texas, who redshirted as a freshman last fall, posted his departure on Instagram on Tuesday: "I was blessed with to become a Hawkeye (sic). But now it's time I pursue some of my other goals in life and take advantage of new doors that have opened in other areas of my life. My memories here will live on forever."

It's been a year of many ups and downs, and I'm more than grateful for the opportunity I was blessed with to become a Hawkeye. But now it's time I pursue some of my other goals in life and take advantage of new doors that have opened in other areas of my life. My memories here will live on forever. #onceahawkalwaysahawk

Graham's departure was confirmed by HawkeyeReport.com's Blair Sanderson on Tuesday night. The Prattville, Ala., native was an 11th-hour addition to the 2015 class after Karan Higdon defected from Iowa to Michigan on National Signing Day. With Graham out of the picture, that could open an opportunity for incoming freshmen Toks Akinribade and/or Toren Young to play right away.

Neither Graham nor Jinning was listed on Iowa's depth chart this spring.

Iowa's summer conditioning program for returning players began Monday.
