Northwestern senior quarterback Aidan Chiles is set to miss his second straight game Saturday at No. 20 Ohio State, according to Wednesday's Big Ten injury report.
Chiles has been dealing with an upper-body injury, and his timeline for a return remains uncertain, ESPN's Pete Thamel reported last week.
Nicco Marchiol, a transfer from West Virginia, started in Chiles' place in last weekend's 24-10 loss to Iowa. Marchiol completed 24 of 32 passes for 181 yards and a touchdown but took six sacks. He also rushed for 52 yards on 23 carries.
Chiles, who has given the Northwestern offense a major boost this season after transferring in from Michigan State, has thrown for 1,898 yards while accounting for 23 TDs with just one interception. He also ranks 14th nationally with a QBR of 81.3.
Ohio State has lost its last two games. Last weekend, Oregon backup quarterback Dylan Raiola threw for 257 yards in the Ducks' 41-28 victory over Ohio State.
