ENGLEWOOD, Colo. — Quarterback Drew Lock returned to practice on a limited basis on Thursday as the team continued to prepare for the Dolphins.

Lock participated in both individual and team reps on Thursday.

The second-year quarterback said he has felt better each day since the game and never believed that he suffered a fracture to his ribs.

"It's been a good process so far with the doctors and all the trainers here," Lock said Thursday. "I got to go out and throw the ball. That's all I could really ask for today. I was excited and ready to get back out there and throw it. I was feeling good."

Lock said he wants to play Sunday against the Dolphins but admitted the final decision will be left up to the medical staff and coaching staff.

"I'm going to take it day by day with these doctors and the trainers and even the coaches," Lock said. "I'm going to let them make a decision on whether or not they want to play me or not and obviously I'll give my opinion, and it's going to be [that] I want to play. In the end, it's not 100 percent up to me what happens."

Tight end Noah Fant also returned to practice Thursday on a limited basis, and Head Coach Vic Fangio said he was "confident" that Fant would be OK to play.

Tackle Jake Rodgers (shoulder) also improved to limited, while linebacker Josey Jewell (quad) and safety Trey Marshall (elbow) improved from limited participants to full participants. Tackle Calvin Anderson (ankle), cornerback A.J. Bouye (hip) and wide receiver Jerry Jeudy (ankle) remained limited. Linebacker Joe Jones (calf) did not practice for the second consecutive day.
