The San Francisco 49ers have little time to focus on the four turnovers, leaky run defense and lack of a pass rush that contributed to their first loss of the season. Coach Kyle Shanahan said Monday that Purdy reported after the game that he had soreness in the toe that sidelined him the previous two games. Purdy needed to undergo more tests to help determine his status this week when the Niners (3-1) visit the division rival Los Angeles Rams on Thursday night.
