Running back Terrance Ganaway, affectionately dubbed The Sandwich Maker because of his offseason job at Jimmy John’s, has decided to call it a football career.

Ganaway, the second-year player from Baylor, is leaving football to pursue a graduate degree. Slowed by a nagging hamstring ailment this preseason, Ganaway had fallen behind rookies Zac Stacy and Benny Cunningham in the battle for backup jobs in the backfield.

Ganaway leaves the Rams without having touched the football via catch or carry in a preseason or regular- season game. Claimed on waivers from the New York Jets at the end of the preseason in 2012, he was on the 53-man roster all season but appeared in only three regular-season games without a touch.

He missed the 2013 preseason opener in Cleveland because of the hamstring issue, and then appeared in nine plays last week on the final drive _ a touchdown drive _ against Green Bay. With the Rams in the two-minute drill, he basically served as a pass protector and didn’t get the ball against the Packers.

So in the matter of three days, the Rams’ running back situation has gained a lot of clarity. Coach Jeff Fisher named Daryl Richardson the starter Monday and now Ganaway is out of the picture. That leaves Isaiah Pead, Stacy, Cunningham, and Chase Reynolds competing for backup jobs and pecking order behind Richardson.

Along with quarterback Robert Griffin III, Ganaway was one of the stars of the 2011 Baylor team, rushing for 1,547 yards and scoring 22 touchdowns. He set or tied 12 school records as a senior and was MVP of the Alamo Bowl. He earned his college degree in general studies in December 2010 and was named multiple times to the Big 12 Commissioner's academic honor roll.
