Video from Miami Dolphins training camp appears to show the moment quarterback Ryan Tannehill injured his left knee Thursday.

On a scramble, Tannehill planted his left leg before falling to the ground in pain. He was wearing a brace on the leg as the result of a December 2016 injury to his MCL and ACL – an injury from which Tannehill recently said he had fully recovered.

The Dolphins haven’t provided an update on Tannehill’s injury but are reportedly fearing the worst.
