49ers quarterback Thaddeus Lewis suffered a torn ACL and is out for the season, according to Ian Rapoport of NFL.com (on Twitter).

Lewis was forced to exit from the Niners’ preseason opener on Sunday night with a leg injury, but the severity of the issue was not immediately apparent. Before his night ended prematurely, Lewis completed 12-of-21 passes for 97 yards against the Texans.
In March, Lewis inked a one-year, $760K minimum salary benefit deal with SF. Although the deal included $25K in playing-time incentives and a $428K split salary, it doesn’t appear that the pact called for much in the way of guarantees.
Lewis, 28, was on the Eagles’ roster when Chip Kelly was their head coach last season and the two reunited in San Francisco this spring. Lewis has appeared in seven NFL games, though none since 2014, making six starts with five touchdowns against four interceptions.
With Lewis out of the equation, the Niners are left with Blaine Gabbert, Colin Kaepernick, and Jeff Driskel at quarterback.
