LINCOLN, Neb. (AP) — Nebraska senior offensive lineman Mike Smith is out for the season because of a broken leg.

Coach Bo Pelini said after Wednesday's practice that Smith was injured during a contact drill on Tuesday. Smith started 14 games at left tackle last season but was expected to play a backup role at guard and center this year.

Offensive lineman Jermarcus "Yoshi" Hardrick missed his second practice in a row after being hospitalized briefly for dehydration Monday. Pelini said Hardrick should be back on the field Thursday.

The Cornhuskers practiced in the air-conditioned Hawks Championship Center for the second straight day. They spent the first three days of practice outdoors, but Pelini said the unrelenting heat beat down his players and was dangerous.
