Penn State linebacker Ben Kline sustained a torn pectoral muscle against Minnesota and will miss the remainder of the season.
Head coach Bill O'Brien said Tuesday that the Dallastown High School graduate, a redshirt sophomore, was injured on the second play against Minnesota but completed the game and made four tackles. Kline will have surgery later this week, O'Brien said.
The injury was another in a series for Kline, who missed three games this season because of a shoulder issue. Kline had shoulder surgery last season and faces another procedure on the shoulder in the offseason.
Kline made his first career starts against Illinois and Minnesota. He finished the season with 18 tackles.
"I can't say enough about Ben," O'Brien said. "We'll miss him."
Freshman Brandon Bell and Stephen Obeng-Agyapong will see more time at linebacker this week against Purdue.
ROBINSON'S INJURY: Receiver Allen Robinson sustained "a little shoulder issue," but O'Brien said he expects the Big Ten's leading receiver to play.
Robinson broke Penn State's single-season record for receiving yards against Minnesota. He sustained the injury in the second half but returned to the game.
O'Brien said several times Tuesday that redshirt freshman receiver Eugene Lewis will see more time Saturday as well.
TURNOVER CON CERNS: Penn State is tied for 105th in the country with a minus-7 turnover margin that has frustrated O'Brien. The Lions fumbled on their first and last offensive plays of the game against Minnesota. Further, Penn State has committed three turnovers in the red zone the past three weeks.
O'Brien said that, though turnovers happen, sometimes they're the result of a "complete lack of focus."
"When you're a ballcarrier on the team, you carry the hopes and dreams of the football team," O'Brien said, later adding that "it's not like we love the kid any less for fumbling."
MILITARY APPRECIATION DAY: Penn State has designated Saturday's game as "Military Appreciation Day." More than 2,000 service members and their families will attend Saturday's game as part of the "Seats for Soldiers program," in which individuals and businesses donated tickets.
Adam Hartswick, a U.S. Army senior combat medic who graduated from State College High in 2009, will participate in the pre-game coin toss. Hartswick lost both legs in an explosion this year while serving in Afghanistan.
NOTEWORTHY: Running back Akeel Lynch returned to practice Monday after missing the past two games with an MCL sprain. Bill Belton and Zach Zwinak will continue to rotate at the position. ... Purdue has the Big Ten's least effective offense, averaging just 11.8 points per game. The Boilermakers (1-8) have scored two touchdowns (both against Iowa last week) in their last four games.
