The San Francisco 49ers have released their first injury report of the season. The team is preparing to host the Los Angeles Rams in their season opener on Monday night.

CB Chris Davis' unavailability was not unexpected. He has been unable to practice all week. Davis had been expected to be the 49ers' primary nickel corner and most likely would have been tasked with the duty of covering Rams WR Tavon Austin in the slot on Monday night.

OG Anthony Davis did not practice on Saturday due to what was described as a personal matter. He had practiced during the rest of the week. Davis is the starting right guard along the offensive line. Cam Inman of Bay Area News Group reports that Davis may once again be contemplating retirement – this time on the eve of the team's season opener.

CB Keith Reaser, who did not practice Thursday, was in full pads on Friday, but was limited. He too is listed as questionable.

Below is the complete injury report, which was released by the team. The status of "probable" was eliminated this season, leaving only "questionable," "doubtful," and "out."
