New Orleans Saints cornerback Keenan Lewis practiced fully on Wednesday, confirming that he will almost certainly play Saturday against the Seattle Seahawks.

However, the Saints were without running back Pierre Thomas (chest), who appears to be a long shot to return this weekend.

Guard Jahri Evans (ankle) and defensive end Akiem Hicks (ankle) were both limited on Wednesday.

Lewis' value to the team was more apparent than ever last week when he left the Saints' 26-24 victory over the Philadelphia Eagles with a concussion late in the third quarter. The Eagles began picking on the Saints' young cornerbacks after that.

Lewis, who insisted Tuesday that he would be back this week, has been a vital part of the Saints' defensive success this year as a No. 1 cornerback who routinely matches up against the opponents' top receivers in man coverage.

Thomas has also been a big part of the Saints' success this season as a do-everything running back (running/receiving/pass protection). However, the Saints are deep at the running back position -- which they proved during Thomas' absence last week at Philadelphia. Mark Ingram ran for 97 yards and a touchdown. Rookie Khiry Robinson ran for 45 yards and Darren Sproles gained 60 yards from scrimmage.
