Senior running back Mark Allen will miss the rest of the season. Head coach James Franklin shared the unfortunate news on Tuesday afternoon at his weekly news conference in advance of this weekend's Ohio State game.

Allen is one of eight fifth year seniors that make up the remaining members of James Franklin's first recruiting class at Penn State back in 2014. He will end his Nittany Lion career with 90 carries, 353 yards, and four touchdowns to go along with 12 receptions for 93 yards, and one more score. His final action in the blue and white came in the third quarter against Kent State, appropriately enough on a seven yard touchdown run.

There is no word on the nature of the injury. During Friday night's broadcast, however, FS1 mentioned Allen had been injured in practice leading up to the Illinois game.

With Allen's injury, true freshman Ricky Slade will take over the backup role behind Miles Sanders. Allen's classmate, Johnathan Thomas, and redshirt freshman Journey Brown will handle third string duties. Slade has carried the ball 25 times for 147 yards and four touchdowns. Thomas' only action came late against Kent State, where he had three carries for 84 yards and a score, the first of his collegiate career. Brown saw his first ever action for Penn State against the Illini, carrying the ball twice for 10 yards and his first career touchdown.
