All of the speculation regarding the severity of Tom Brady’s left knee injury ended on Monday, when the New England Patriots placed him on the injured reserve. The move effectively ends Brady’s 2008 season, confirming what was widely reported on Sunday.

The Patriots released a statement saying Brady’s injury would require surgery, but didn’t confirm the specifics of the type of injury he suffered.

“That’s really about all we have at this point,” Patriots coach Bill Belichick said in a Monday news conference. “Of course we feel badly for tom about the injury, you hate to see anyone go down. Nobody works harder than Tom. .. It’s a tough setback for him.”

Belichick went on to dispute reports that the Patriots had already worked out several quarterbacks, saying the team had only fielded calls.
