During the San Francisco 49ers' 31-21 win over the New York Giants in Week 10, quarterback C.J. Beathard injured his right thumb.
Per Cam Inman of the Bay Area News Group, Beathard is expected to have an X-ray on his thumb soon.
Inman also noted that San Francisco's offensive players were told Jimmy Garoppolo would be coming in after Beathard injured his thumb, but the rookie quarterback was able to fight through the pain to remain in.
There was no indication during the game that Beathard was injured.
