Peyton Manning practices again for Denver Broncos

Quarterback Peyton Manning was able to make it through a full practice on Thursday and could be active for the first time in seven games on Sunday when the Denver Broncos face the San Diego Chargers.

If Manning avoids any setbacks, he will back up starter Brock Osweiler in the regular-season finale, coach Gary Kubiak said.

"He's moving around, got a lot of reps today," Kubiak said. "The confidence comes more each day."

Safeties T.J. Ward (ankle), Darian Stewart (hamstring) and Omar Bolden (hamstring) also made it through practice for the second straight day.

The only Broncos player who did not practice Thursday was linebacker Brandon Marshall (ankle sprain). He hasn't been ruled out of Sunday's game yet but is unlikely to play. Marshall's replacement would be linebacker Todd Davis.
