Ray Edwards' loss is Kroy Biermann's gain for the Atlanta Falcons.
Biermann took over as a starting defensive end earlier this week after the Falcons cut Edwards.
Cliff Matthews and rookie Jonathan Massaquoi also are likely to earn more playing time when Atlanta (8-1) hosts Arizona (4-5) on Sunday.
Biermann originally lost the left end job when the NFL lockout ended last year. Atlanta signed Edwards and gave him $11 million guaranteed.
But after watching Biermann flourish in the scheme designed by first-year defensive coordinator Mike Nolan, the Falcons decided that Edwards was no longer needed.
Right end John Abraham, the NFL's active career sacks leader, says Biermann is a consummate team player who does whatever he's asked.
That didn't seem to be the case with Edwards.
