The 49ers didn't exercise their team option on Mitchell, making him a free agent, Matt Maiocco of NBC Sports Bay Area reports.
Reports first leaked shortly after the season indicating the 49ers didn't plan to pick up Mitchell's option, but the transaction didn't become official until the start of the new league year. The 31-year-old nose tackle is free to sign with any team after posting 17 tackles and no sacks across 14 games last season.
