A day after finalizing their initial 53-man roster (which has unshockingly already undergone several changes), the San Francisco 49ers got to work on Wednesday filling out their practice squad.
While the Niners only officially announced 13 signings on Wednesday (each team is allowed 16 players, 17 if one is part of the league's International Player Pathway Program), not one of them was a quarterback.
However, when general manager John Lynch was asked by NBC Sports Bay Area about the situation, he confirmed that San Francisco did indeed have a quarterback set to join the practice squad on Thursday, that being 25-year-old Adrian Martinez, who was cut by the New York Jets earlier this week and will now serve as the 49ers' QB3 behind Brock Purdy and Mac Jones.
