All-Pro cornerback Darius Slay (pictured above) was back at practice in Allen Park on Friday as the 0-2 Detroit Lions prepare to face the New England Patriots Sunday night at Ford Field, according to the Detroit News.

However, starting left tackle Taylor Decker missed practice because of an undisclosed injury.  He is not listed in the Week 3 NFL Injury Report as of Friday afternoon.

Slay is listed as Questionable for Sunday's game.  He suffered a concussion in the 2nd Quarter of last Sunday's loss to the San Francisco 49ers and missed the remainder of the game.  He has been in the NFL's Concussion protocol since then.

Also, defensive end Ziggy Ansah is listed as Questionable for Sunday's game with a shoulder injury.
