Nebraska redshirt freshman Tommy Armstrong will start for the third consecutive game Saturday at Purdue in place of injured senior Taylor Martinez, Cornhuskers coach Bo Pelini said Thursday after the team completed its week of practice.

"Taylor is still day to day, and he is getting better," Pelini said of the school's all-time leader in total offense, who has been hobbled by turf toe on his left foot. "He is a lot better than he has been."

Martinez, the fourth-year starter, has not played since Nebraska's Sept. 14 loss to UCLA. Nebraska (4-1) is off next week. By the time it plays Oct. 26 at Minnesota, Martinez will have sat for five weeks.

Armstrong will again share time with senior Ron Kellogg III, Pelini said. Kellogg played in the first halves of Nebraska wins against South Dakota State and Illinois.

Armstrong has completed 20 of 28 passes in his two starts for 304 yards and three touchdowns without an interception. He leads the Big Ten in QBR (88.2), completion percentage (71.4), yards per attempt (10.86) and yards per completion (15.2).

Pelini said Martinez would travel with the Huskers on Friday to West Lafayette, Ind.

Receiver Jamal Turner, bothered by a hamstring injury this week, practiced Thursday and will play against the Boilermakers (1-4), according to Pelini.
