Lincoln -- The Nebraska football team completed its second two-a-day practice on Wednesday during a two-hour and 20-minute afternoon workout in full pads on the grass fields adjacent to Memorial Stadium.

Wednesday's afternoon workout followed a morning workout in half pads in Memorial Stadium, and Nebraska head coach Frank Solich said the Huskers are beginning to battle fatigue and soreness during their workouts.

"It was a long day for them today with a two-a-day again, but they seem to be working through it very well," Solich said. "We're getting our fair share of bumps and bruises, some minor injuries and an injury that will keep DeAntae (Grixby) out for four to five weeks."

Solich said Grixby suffered an ankle and foot injury on Tuesday, which will likely be casted for approximately three weeks.

"It has been tough on DeAntae, coming off his last injury and he has had shoulder problems," Solich said. "He's had enough things that have interrupted him having any flow to his practices, so that has been very difficult for him. He has battled through each of those, and he will battle through this one. He was playing very well, and he would have gotten playing time at the fullback spot. He is also important to us on special teams."

Solich said the Huskers may add some live snaps in goal-line situations during Thursday's afternoon practice scheduled for 3:30 p.m.
