Detroit Lions coach Jim Caldwell did not disclose a timetable for Nick Fairley's return after the defensive tackle injured his right knee in a win over Atlanta on Sunday.

Caldwell says he's aware of a report that Fairley could miss around a month, but says the Lions haven't come to that conclusion yet. He says he's received no indication that the injury is season-ending.

Fairley was injured as he hit Falcons quarterback Matt Ryan on a pass play. Lions teammate Ndamukong Suh, rushing Ryan from the other side, crashed into Fairley.

After falling awkwardly, Fairley clutched his right knee and was noticeably limping as he was helped off the field.

Detroit has an open date this weekend, then hosts Miami.
