Tannehill missed the previous game against the Houston Texas due to the ankle as well as an illness and was a limited practice participant on Friday after sitting out Thursday's workout. Vrabel referred to Tannehill's situation as day to day and said he wouldn't be surprised if a decision doesn't come until Sunday.
"I think so," Vrabel said. "We'll keep you updated."
If Tannehill can't play, third-round draft pick Malik Willis will make his second straight start. Willis completed 6 of 10 passes for 55 yards and one interception in the 17-10 win against Houston.
"It's going to be a great environment," Willis said.
