Pelini said during the Big Ten coaches' teleconference that an evaluation of Long, a Huskers co-captain, showed less damage than originally feared. Still, the first-team All-Big Ten pick by ESPN and second-team Associated Press All-American will undergo surgery Thursday.
Long, a three-year starter, was injured on a running play during Nebraska's opening possession in a 44-7 victory against Purdue on Saturday. Long fell over Boilermakers defensive end Ryan Russell as he was trying to block on the backside of a rush by Imani Cross.
A former walk-on from Omaha, Neb., Long has started 33 games since 2011.
He was the most experienced member of an offensive line that has helped the Huskers (5-1, 2-0 Big Ten) average 284.8 rushing yards per game, which ranks eighth nationally. Additionally, Nebraska has allowed three sacks in six games, tied for the fewest nationally with Fresno State, Northern Illinois and Toledo.
Sophomores Givens Price and Ryne Reeves may also receive more playing time as a result of the injury. Newcomer Chongo Kondolo, a junior college transfer who is on target to redshirt this season, could also factor, Pelini said.
"We're looking at all our options," Pelini said.
