Denver Broncos quarterback Peyton Manning has admitted that he was below-par in his side's defeat to the St Louis Rams.
Manning was held to his lowest points tally as a member of the Broncos as the Rams limited John Fox's men to just seven points at Edward Jones Dome.
The 38-year-old also threw two interceptions in the game as his side slipped to their third defeat of the season.
He told reporters: "I didn't play well ... I give them a lot of credit, but I've got to play better."
Julius Thomas and Emmanuel Sanders also sustained injuries in Denver's defeat to the Rams.
