FLOWERY BRANCH, Ga. (AP) — The Atlanta Falcons will be without a key member of their cornerback rotation for the second week in a row after ruling Kendall Sheffield out of Sunday's game against the Dallas Cowboys.

Sheffield is still recovering from a foot injury and wasn't able to practice all week. He also missed the season opener against the Russell Wilson and the Seattle Seahawks, who completed 31 of 35 passes for 322 yards and four touchdowns in a 38-25 victory.

The Falcons also ruled out backup defensive end Charles Harris (ankle), while rookie defensive tackle Marlon Davidson (knee) was listed as doubtful. Both also missed the opener.

Starting left tackle Jake Matthews (knee) is questionable after only taking part in a limited part of practice the past two days.
