Ja'Marr Chase's frustrations came to the boil on Monday night, with the Bengals star confronting head coach Zac Taylor and then accusing his teammates of 'giving up'.
Cincinnati - already without injured quarterback Joe Burrow - saw its season go from bad to worse with a 28-3 rout by the Broncos in Denver.
Taylor's offense ended the game with just 159 yards, while Cincinnati also surrendered 11 penalties for 65 yards.
During the second half, star wide receiver Chase - who signed a $161million extension earlier this year - was seen in a heated conversation with Taylor on the sideline.
Later, after the Bengals fell to 2-2 for the season, Chase aired his frustrations in the locker room.
'The urgency is there, it's just you gotta want it,' the receiver told reporters. 'At the end of the day, we gotta want it. Today, it didn't look like we wanted it.'

'All he wants to do is win the game. All he wants to do is affect the game,' Taylor insisted
When asked to clarify his comment, Chase accused the Bengals of 'just giving up'. He also addressed his clash with Taylor.
'We were just talking about the possession,' Chase insisted. 'We were just talking about what plays we can run and how can we attack certain coverages and get our playmakers the ball.'
Chase ended the night with five receptions for just 23 yards as Cincinnati saw its final eight possessions end in punts. But Taylor also played down their sideline conversation.
'It comes across as emotional, but that's just a captain that works his tail off,' the head coach said. 'All he wants to do is win the game. All he wants to do is affect the game. Often times, he feels like, "If I have the ball in my hand, I can do that." And I don't disagree with him.'
Quarterback Jake Browning, who has replaced Burrow under center, disputed that the team's problem is a lack of commitment.
'I don't question anybody's effort in the locker room,' he said. 'I don't think that's how everything goes for the Bengals.'
