Patrick Willis and Nnamdi Asomugha have missed practice with the San Francisco 49ers for a second day.
The linebacker sustained a groin injury during the team's 27-7 defeat to the Indianapolis Colts in the NFL on Sunday, while Asomugha has a knee problem.
The duo were the only players not to take to the practice field yesterday, while tight end Vernon Davis, who missed Sunday's game with a hamstring injury, was limited.
The 49ers face NFC West rivals the St Louis Rams on Thursday.
