Miami Dolphins left tackle Terron Armstead tweeted he is aiming to be ready for the team's regular season opener, after leaving Thursday's practice with a knee injury.
Armstead injured his right leg on the first play of team drills during a joint practice with the Houston Texans; medical trainers eventually took him back to the locker room on a cart. The four-time Pro Bowler posted a video of himself walking after practice and was seen leaving the training grounds with crutches.
A source close to the situation told ESPN that Armstead's injury didn't appear serious, although further testing and evaluation needed to take place before a timetable was determined.
