Knocking the air out of the Cleveland Browns left him winded.
Atlanta's defensive end leaped to tip a pass, caught the deflection with a headfirst dive, rolled on the ground, alertly jumped to his feet and outran a few Cleveland players for a spectacular touchdown in the fourth quarter, giving the Falcons a 20-10 win over the battered Browns on Sunday.
The play was rough, rugged and rowdy -- like Biermann.
"Kroy is from Montana," Falcons coach Mike Smith said. "He has probably rode a few wild broncos and bulls and been thrown off and landed on his feet. It was just a super athletic play."
With the Falcons up 13-10, Biermann sniffed out a screen pass as he pressured Browns quarterback Jake Delhomme on third-and-7. Biermann jumped to bat Delhomme's pass high in the air and then hustled to snare it, catching the ball just above the turf like a seasoned wide receiver.
Knowing he had not been touched and could still run, Biermann hopped up and rumbled 31 yards, dragging a final defender into the end zone to make it 20-10 with 4:01 left.
"That was the trifecta right there," an impressed Falcons running back Michael Turner said. "A tremendous play. You can't get better than that. I didn't critique his technique. I was too busy cheering."
After his first career interception as a pro and the only one he could remember since junior high, the 6-foot-3, 260-pound Biermann, a fifth-round pick in 2008, was mobbed by his excited teammates as he laid breathless in the end zone.
"The right play at the right time," he said. "Once I caught it, I just got to my feet and started to run. I was glad it all worked out."
Atlanta quarterback Matt Ryan threw a 45-yard TD pass to Roddy White as the Falcons (4-1) won their fourth in a row since a season-opening overtime loss in Pittsburgh. Turner rushed for 140 yards, including a season-long 55-yarder, and White added 101 yards on five catches.
The Browns (1-4) are bruised all over.
They lost quarterback Seneca Wallace just before halftime with an ankle injury. Wallace made his fourth start in a row for Delhomme, who had been out since Week 1 with a severely sprained right ankle. Wallace will undergo further tests, but could be sidelined several weeks
