Trufant missed the last two games with a shoulder/pectoral injury. Wile excelled in his NFL debut last week against Arizona, averaging 58 yards on two punts and having touchbacks on each of his seven kickoffs. He was an injury fill-in for Matt Bosher, who is expected to return for this week's game against Kansas City.
Wreh-Wilson started in 14 of his 34 games the last three years for Tennessee and was waived before the season. Robinson has spent time with the Bengals and Chargers.
The Falcons also signed offensive lineman Kevin Graf to their practice squad.
