Dolphins defensive tackle Paul Soliai (knee) and cornerback Dimitri Patterson (groin) both key starters are listed as "out" for Sunday's game against Atlanta.
That could be a boost for the Falcons who will be without five injured starters when they visit Sun Life Stadium.
The good news for Dolphins fans is quarterback Ryan Tannehill (shoulder) was upgraded to probable and safety Chris Clemons (hamstring) was upgraded to questionable.
However wide receiver Mike Wallace (groin) and center Mike Pouncey (ankle) were downgraded to questionable after their limited participation in Friday's practice. Linebacker Koa Misi (knee) is also questionable. All are expected to start Sunday.
Wallace who had nine receptions for 115 yards and a touchdown last week against Indianapolis battled a groin injury during training camp that kept him out of the Hall of Fame game. But he hasn't showed any lingering affects so far.
