ENGLEWOOD, Colo. -- Denver Broncos quarterback Peyton Manning was officially listed as limited in Friday’s practice because of a right thigh injury, but Manning threw more than he did in Thursday’s practice as the Broncos close in on Monday night’s game in Cincinnati.

Manning participated in the walk-through and threw in individual drills Friday and is still on track to start against the Bengals in Paul Brown Stadium. Other than when he missed the 2011 season because of spinal-fusion surgery Manning has not missed a start in his 16 other NFL seasons.

Thursday Manning participated in the Broncos’ walk-through, went through the team stretch and then went back into the Broncos’ complex to get treatment on his leg. Friday he remained in the field for practice, throwing throughout the portion open for viewing.

“He’s improving, I thought he had good work out there [Friday],’’ said Broncos head coach John Fox, following Friday’s practice.

Manning, who played last Sunday’s game with flu-like symptoms after getting four IVs Saturday night and Sunday morning combined, injured his thigh on a rollout with 5 minutes, 39 seconds remaining in the first half.

He stayed in the game for the next eight plays, but gave way to Brock Osweiler, who finished out the first half. Manning went on to play the entire second half.

Also Thursday, linebacker Brandon Marshall (left foot) and tackle Paul Cornick (toe on right foot) did not practice.

Running back Juwan Thompson (hip, knee), who was held out of Thursday’s practice, took part in Friday’s on a limited basis. Also limited were running back Ronnie Hillman (left foot), left tackle Ryan Clady (right thigh), center Will Montgomery (knee) and cornerback Kayvon Webster.

Tight end Jacob Tamme (ribs), who had been limited in Thursday’s practice, was a full participant in Friday’s practice. Wide receiver Demaryius Thomas (right ankle), Anderson (left ankle) and tight end Julius Thomas (left ankle) all took part fully in Friday’s practice.
