Detroit Lions wide receiver Calvin Johnson may need knee surgery, ESPN reported Sunday.
Doctors recommend that Johnson undergo arthroscopic surgery on his sprained knee this offseason to ease swelling and to clean out loose bodies, according to the report.
Johnson and the Lions will make a decision about the surgery after they wrap up their season Sunday against the Minnesota Vikings.
Johnson, the NFL's second-leading receiver with 1,492 yards this season, will not play the finale because of the injury.
He could skip surgery, but there is a chance he may further aggravate the injury if he simply rests and lets the knee heal on its own.
In addition to gaining nearly 1,500 receiving yards, Johnson made 84 catches and scored 12 touchdowns, despite missing one game against the Green Bay Packers in October. He has also been limited the past few weeks.
Johnson, 28, has six years remaining on his eight-year, $132 million contract. The deal made him the highest-paid player in the NFL.
