Adrian Martinez Returns to 49ers Practice Squad After Jets Stint

The San Francisco 49ers have signed quarterback Adrian Martinez back to their practice squad, making him the fourth quarterback in their building. Martinez has had a dynamic season, bouncing between the 49ers' practice squad and 53-man roster, and briefly spent time with the New York Jets' practice squad last week. He previously appeared in one game for San Francisco, taking a knee to conclude their November 2nd victory over the Giants.
