The Lions lost a starter on defense Saturday, but gained one back on offense Sunday.
The team downgraded starting defensive end Ziggy Ansah from questionable to out Saturday afternoon. Ansah hasn't played since Week 1 because of a shoulder injury he suffered in the second quarter of that loss to the Jets. He has practiced on a limited basis the last couple weeks.
The good news for the Lions on the injury front is they are get starting right guard T.J. Lang back for today's contest in Miami. He was questionable coming in after missing Detroit's last game with a concussion, but Lang cleared the NFL's concussion protocol and is active.
The Lions will be without another starter on offense, running back Theo Riddick, however. Riddick missed all week of practice due to a knee injury. He was ruled out on Friday's injury report.
Running back Ameer Abdullah is active for a second straight week, and could see some run in the backfield with Kerryon Johnson and LeGarrette Blount with Riddick on the mend.
Second-year tight end Michael Roberts is back in action for the Lions for the first time since Week 2. He has been battling a knee injury and hasn't played since catching a touchdown pass the second game of the season in San Francisco.
Joining Ansah and Riddick on Detroit's inactives list today are: Tackle Andrew Donnell, wide receiver Brandon Powell, guard Joe Dahl, defensive end Kerry Hyder Jr. and cornerback Lenzy Pipkins.
