49ers safety Don Jones posted on his Snapchat that he suffered a torn left ACL in the team’s preseason finale against the Chargers on Thursday, per James Brady of Niners Nation. He’s now likely to head to injured reserve, according to Matt Maiocco of NBC Sports Bay Area (Twitter link). Placing Jones on IR would reduce the 49ers’ roster to 70 players, 17 above the 53-man limit.
Jones joined the 49ers on a two-year deal at the outset of free agency in March, before which the 2013 seventh-round pick spent time with six organizations. He divided 2016 between Cleveland and Houston and appeared in 13 games, logging his first-ever start along the way.
While Jones is technically a defender, playing time has been scarce on that side of the ball for the 27-year-old. Jones has mainly functioned as a special teamer, and he played nearly 40 percent of the Texans’ ST snaps during his nine-game stint with them last season.
