ALLEN PARK -- Lions wide receiver Calvin Johnson and cornerback Chris Houston did not practice today (Thursday). It’s the second straight day that each of the starters has missed practice.

Johnson re-injured his ankle in Sunday’s win at Miami. It’s a possibility he could play on Sunday against the Vikings at Ford Field even if he does not practice all week.

Houston injured his shoulder on Sunday and has not been ruled out to play the Vikings.

LB Landon Johnson (concussion) is out and was expected to be placed on injured reserve. But that has not happened yet.

Cornerback Tye Hill who missed Wednesday’s practice with an illness was back at it today.
