The news about the knee injury Sam Bradford suffered in the St. Louis Rams’ preseason game initially was hopeful, but by Sunday afternoon it was dimming fast.

The quarterback, whose NFL career has been marred by injuries, tore the anterior cruciate ligament in his left knee, the one on which he underwent surgery last November. Never mind that he was walking around after the game, ESPN’s Chris Mortensen reported Sunday afternoon that Bradford had gotten bad news from an MRI again. With Bradford out, Shaun Hill, who hasn’t started since 2010, would be expected to take snaps with Austin Davis at backup. Unless, of course, the Rams make a move.

This was considered to be a make-or-break year for Bradford, the No. 1 pick in the 2010 draft, after a 2013 season in which he played well but lasted seven games. Bradford, the last of the draft picks to cash in with a big rookie contract, got $50 million guaranteed. Bradford played all 16 games in his rookie season, but has been injured since then. Under the 2011 collective bargaining agreement, Cam Newton got $22 million as the No. 1 pick the next year.

Rams Coach Jeff Fisher is expected to address the media late Sunday afternoon.
