Calvin Johnson expected to play despite knee injury

The Detroit Lions have listed Calvin Johnson as probable for their game against the Pittsburgh Steelers this weekend.

The wide receiver missed two days of practice this week with a knee injury, but was able to return yesterday.

The 28-year-old missed a game with the same injury earlier in the season, but has returned to form in recent weeks, scoring five touchdowns in his last three games.

However, the Lions expect to be without Nate Burleson, who is continuing to recover from an arm fracture.
