Two key Nebraska players will be out for the remainder of spring practice, head coach Scott Frost announced on Wednesday.

Defensive lineman Ben Stille and transfer running back Markese Stepp will be out for spring camp. Stille reportedly had surgery before the start of the spring schedule and it will keep him sidelined. Stepp is expected to be back for the summer months.

Stille is entering his fifth season with the Huskers, having played in 41 career games. He’s racked up 107 tackles, including 24 for loss and 13 sacks with 4 passes defended and a forced fumble.

His presence in spring practice probably isn’t critical, having been in the program for four seasons. The big question is whether Stille will be healthy enough to return for Nebraska’s season opener against Illinois in Week 0.

Stepp transferred into the program after spending the last three seasons at USC. He’s played in 14 career games with 505 rushing yards and 6 touchdowns on the ground as a Trojan. This is his first spring camp with the Huskers.

Per Sam McKewon of the Omaha World-Herald, there are multiple Huskers who will miss spring camp.
