Keenum didn’t want to miss Wednesday’s workout but said he understood that being cautious in September will give him a better chance of staying in the lineup all season.
Keenum has led the Broncos (2-0) to a pair of fourth-quarter comebacks, pushing his record over the last two seasons to 13-3.
He helped the Minnesota Vikings reach the NFC championship game last year before signing a two-year, $36 million free agent contract with Denver.
The Broncos play at Baltimore (1-1) on Sunday.
