Back at practice
Mostert (knee) was spotted at Thursday's practice, David Furones of the South Florida Sun Sentinel reports.
Mostert didn't practice Wednesday, which Cameron Wolfe of NFL Network suggested was rest and maintenance-related. Now that he's back on the field, Mostert is trending toward active status Sunday night against the Patriots, though he'll probably need to log a full practice by Friday in order to avoid a Week 2 injury designation.
