Calvin Johnson misses Detroit Lions practice again

Calvin Johnson has missed a second day of practice with the Detroit Lions.

The wide receiver has sat out for the last two days with a knee injury, which has been hindering him since September.

The 28-year-old has regularly missed practices since sustaining the knock, but has not missed back-to-back sessions in recent weeks.

Johnson has 567 receiving yards and five touchdowns during the NFC North leaders' last three games.
