Kubiak bemoans Broncos penalties

Denver Broncos head coach Gary Kubiak has vowed to improve their ill-discipline after losing their unbeaten streak to the Indianapolis Colts.

The Broncos gave up four penalties in the Colts' final drive which helped Andrew Luck lead his side to the 27-24 victory, and Kubiak now wants the team to be more mindful of their actions.

"We have to find a way in the second half of the season to turn that around," Kubiak said. "That starts with me, Wade and the coaches and players' responsibility.

"You're going to have some penalties at times, but you can't have selfish penalties that hurt the football team. That has been addressed. We will go to work on getting that taken care of."

Although it is an issue that needs to be addressed, Kubiak does not want the solution to come at the expense of becoming weaker.

"We're going to maintain our aggression as a team," Kubiak added. 

"I don't ever want to take that away, but we've got to make sure that we're thinking about the team in every situation, in everything we do."

The Broncos are also facing an anxious wait over linebacker DeMarcus Ware, who re-injured his back during the defeat.

"There's concern," Kubiak admitted. 

"I know he wasn't feeling very good after the game at all and I talked to him via text, kind of bus-to-bus when we were coming from the airport back home, and he told me he was feeling better.

"But we start over today and we'll have to see how much ground we can make up."
