St. Louis Rams quarterback Sam Bradford is out for the year with a torn ACL in his left knee, according to ESPN.
Bradford injured his surgically repaired knee and limped off the field during the first quarter of Saturday's preseason game at the Cleveland Browns.
Initially, no damage was detected to the same knee that underwent surgery for a torn ACL last season. However, an MRI exam taken Sunday reportedly revealed the injury.
Coach Jeff Fisher is expected to confirm the injury later in the day.
Bradford was hurt with 8:19 left in the opening quarter when Browns defensive lineman Armonty Bryant contacted the quarterback after he released a pass.
After Bradford fell to the turf Saturday, Rams medical personnel and trainers hurried onto the field and then helped him to the locker room. Fisher also came on the field to check on Bradford's condition before Bradford limped off favoring the knee.
Bradford, the No. 1 overall pick in the 2010 NFL Draft, completed 4 of 9 passes for 77 yards. Shaun Hill replaced Bradford.
The Rams stated all offseason their commitment to Bradford. Given opportunities to pursue other quarterbacks, including via the draft, St. Louis turned away and instead invested in Bradford's supporting cast. Twice in the first round of the 2014 draft, the Rams had a chance to select a quarterback of their choice. Blake Bortles went third overall, one pick after St. Louis drafted offensive guard Greg Robinson. And with a second pick in that round, the Rams went with defensive tackle Aaron Donald while Louisville's Teddy Bridgewater and Texas A&M's Johnny Manziel were available.
