Some college football fans hoping to watch Saturday’s Iowa-Iowa State game on satellite television could be left staring at a blank screen.

A contract negotiation impasse between the Big Ten Network and satellite provider DISH Network could lead to the Big Ten Network being dropped from the satellite service Saturday, hours before the Hawkeyes and Cyclones renew their rivalry at Kinnick Stadium at 2:30 p.m.

A short-term agreement between the two businesses prevented that from happening one week ago, allowing the first weekend of college games on BTN to be seen by DISH Network subscribers, but that agreement is set to expire tonight.

On its website, BTN officials warn DISH subscribers that the three games it is televising Saturday might not be available.

“As of Saturday, DISH may drop the BTN. If we don’t reach an agreement before Saturday, it’s unlikely there will be another short-term agreement to show Saturday’s games, including the Cy-Hawk game, on DISH,” BTN vice president of communications Elizabeth Conlisk said.

Last-minute deals can be struck. Last weekend’s short-term agreement was announced shortly after 2 a.m. Saturday.

Subscribers to Mediacom and DIRECTV will not be impacted by the dispute and will be able to view this weekend’s Big Ten Network games as scheduled.
