MADISON, Wis. -- Iowa tight end Erick All was carted into the locker room in the first quarter of the Hawkeyes' 15-6 win over Wisconsin on Saturday, leaving the Hawkeyes without their top playmaker on offense.
All got hurt while making a 5-yard catch on the Hawkeyes' second series. He was helped to the sideline before eventually being taken to the locker room.
"It's not good," Iowa coach Kirk Ferentz said after the game. "We'll know early next week. It's tough. Like everybody who's been hurt this year, it's just really tough for the individual. I wish I had good news. I don't have bad news yet. We'll know Monday or Tuesday."
It was the latest setback for an offense that already lost starting quarterback Cade McNamara to a season-ending knee injury and tight end Luke Lachey to a likely season-ending ankle injury.
At the time of his injury, All had 14 of the Hawkeyes' 28 receptions, 218 of their 346 yards receiving and both of their touchdown catches this season.
Iowa traditionally relies heavily on its tight ends. The Hawkeyes won 20-14 over Purdue last week despite not completing a single pass to a wide receiver.
