Denver Broncos coach Gary Kubiak insisted Peyton Manning remains their quarterback while also taking the blame for his dismal showing against the Kansas City Chiefs.
Manning surpassed Brett Favre to become the NFL's all-time leader in passing yardage with a four-yard completion to Ronnie Hillman in the first quarter of Sunday's game.
But that moment was the lone highlight in an extremely disappointing day in which he threw four interceptions before being benched for deputy Brock Osweiler in the third quarter of the 29-13 loss at Sports Authority Field at Mile High.
However, Kubiak accepted responsibility for the defeat after opting to play Manning despite the 39-year-old - who had already been struggling with foot and shoulder problems - complained of a rib injury after Saturday practice.
"I was protecting him [Manning] because I was worried about him," Kubiak said of the decision to bench the five-time league MVP.
"I'm disappointed in myself, this is on me. I probably should have made a decision not to play him in the game.
"Saturday, his ribs were bothering him a little bit and I probably should have said right there 'no you're not going to go this week'.
"He's a competitor. He wanted to go, he felt like he could go but I'm disappointed in myself because I probably should have made that decision yesterday and I didn't."
Asked if Osweiler would start against this Sunday against the Chicago Bears, Kubiak replied: "Peyton's our quarterback, if he's healthy and ready to go Peyton's our quarterback."
Manning, for his part, refused to blame his fitness problems for his poor play, saying: "I have a really hard time using my injuries as an excuse. I have a hard time saying that's why I played badly.
"I was very honest with [athletic trainer Steve Antonopulos] Greek and coach Kubiak. I wanted to be out there for my team. But I certainly didn't play well, and I am disappointed about that.
"It was a bad game. I put our team in bad positions all day. I was going out to help the team, and I ended up hurting the team. I have to stop turning the ball over."
