That’s the same knee Davis tore up last season as he was emerging as one of the division’s best defensive players. It’s likely Davis, who signed a $3.3 million tender as a restricted free agent, will miss the entire 2010 season.
Davis suffered the second injury in a Tuesday workout.
With James Anderson expected to move into a starting job at one outside linebacker spot, the Panthers have veteran Jamar Williams and a host of young linebackers as candidates to take Davis’ spot. Dan Connor, who has been working at backup middle linebacker, now could become a candidate to move outside.
