ENGLEWOOD, Colo. — After having his practice workload increased over the course of the week, outside linebacker Bradley Chubb (ankle) is listed as questionable for the Broncos' Week 2 game against the Jaguars.

While Chubb's Wednesday and Thursday work were "about the same" — meaning 12 to 15 plays in addition to individual period, according to Head Coach Vic Fangio on Thursday — Chubb was able to do more on Friday as the team wrapped up its three days of on-field preparation.

"Hopefully he'll be able to make it, but we'll see," Fangio said.

Chubb was also questionable for the Broncos' season opener against the Giants, but ultimately he was held out to continue his recovery. Fangio said that the team will evaluate how Chubb feels Saturday and will conduct a walkthrough in Jacksonville.

The team could also be without starting right guard Graham Glasgow, who is doubtful for the game. Glasgow stayed back in New York after Sunday's game to be evaluated for an irregular heartbeat. The medical tests on Glasgow have come back with good news, Fangio said.

"Everything's come back good on him," Fangio said. "All the tests were positive — obviously you're supposed to say negative, but positive as we view it."

Glasgow did not participate in practice during the week, but Fangio said that he will travel with the team to Jacksonville.

Linebacker Jonas Griffith is also listed as questionable for the game. Griffith was added to the injury report on Thursday with a back injury. He was listed as a limited participant on Thursday and Friday.

"During practice yesterday his back tightened up and had to leave practice," Fangio said. "He's fine today."

Defensive linemen Shelby Harris (wrist) and Shamar Stephen (back) were both upgraded to full practice participation on Friday. Harris, Stephen and tight end Noah Fant (knee) did not receive a game status designation on Friday, indicating that they will be available on Sunday.
