Ryan Tannehill could miss an extended period of time after he suffered a high-ankle sprain on Sunday, according to ESPN's Jeremy Fowler and Turron Davenport.
The 35-year-old suffered the injury when he took a sack at the start of the third quarter during the Tennessee Titans' 24-16 loss to the Baltimore Ravens in London. He was carted off the field and did not return.
This was the same ankle that Tannehill had surgery on last offseason, per ESPN's Adam Schefter.
