Nebraska went to halftime without right tackle Jeremiah Sirles, another hit to an offensive line that has taken two big ones in recent weeks.
The NU athletic training staff was looking at Sirles’ left knee after a Husker play with about three minutes left in the second quarter. The fifth-year senior was replaced by sophomore Zach Sterup, who finished the half.
Nebraska already is without starting right guard Spencer Long and left guard Jake Cotton because of knee injuries. It had adjusted its starting lineup Saturday by moving Sirles from left tackle to right tackle so Andrew Rodriguez could move inside to right guard.
Nebraska punted on all three of its second-quarter series and went to halftime with a 10-3 lead.
Also in the first half:
>> Senior receiver Quincy Enunwa got his 100th career catch with a 6-yard reception for a first down in the second quarter.
>> Michigan got its first points with a 27-yard field goal by Brendan Gibbons with 11:47 left in the first half.
>> The Nebraska defense held Michigan to 60 total yards in the first half and sacked quarterback Devin Gardner three times.
>> NU I-back Ameer Abdullah picked up 68 yards on 15 carries in the first half. The junior is trying for his seventh 100-yard game of the season.
>> NU tried Ron Kellogg in a two-minute drill after taking over with 53 seconds left in the second quarter. The Huskers failed to get a first down and punted.
