Iowa’s secondary unit is reportedly taking another hit.

The Hawkeyes would already be without star Riley Moss after sustaining an injury in the win over Penn State. Terry Roberts had been filling in for the injured CB, but it doesn’t sound like that will be the case Saturday.

Per Chad Leistikow of The Des Moines Register, Roberts is in sweats and not participating in warmups as Iowa prepares to take on Wisconsin in a key B1G West showdown.

That will likely put Jermari Harris in the spotlight in the Hawkeyes’ secondary. Northern Iowa transfer Xavior Williams could also be in the mix for Iowa this afternoon.

Moss has been a big loss for the Hawkeyes. He’s totaled 23 tackles, 4 interceptions, 3 pass break-ups and 2 pick-sixes. Roberts has played well, too, piling up 14 tackles, 3 pass break-ups and an interception.

Iowa is 6-1 on the season while Wisconsin is 4-3. Kickoff is set for 12 p.m. ET.
