ATLANTA -- Matt Ryan played two decent series. Matt Cassel played four average ones.
Both quarterbacks lacked solid protection in the preseason opener, but Ryan's Falcons got better play from their rookie reserves in Atlanta's 20-10 victory over the Kansas City Chiefs on Friday night.
Dexter McCluster, a second-round pick, made a few dazzling moves as a tailback and a slot receiver for Kansas City. But Dimitri Nance and Shann Schillinger helped put the Falcons ahead to stay early in the third quarter.
Nance, an undrafted rookie free agent from Arizona State, ran for a 3-yard touchdown to make it 10-3. Schillinger, a sixth-round cornerback, set up the score by picking off Brodie Croyle's throw and returning it 29 yards.
Kansas City safety Eric Berry, the No. 5 overall pick, was credited with one tackle.
The Chiefs had a winless preseason in 2009, then no victories in the first five weeks of the regular season. They finished 4-12 under first-year coach Todd Haley.
Atlanta is coming off a 9-7 season that ended a 44-year franchise history of never achieving consecutive winning records.
The first half was a dud despite McCluster's speedy bursts and a few timely defensive plays by the Falcons.
Five of the first eight drives ended with field-goal attempts. Matt Bryant's 30-yarder on Atlanta's first possession made it 3-0, but the next four tries all missed from 50 yards or more.
Falcons running back Michael Turner, a 2008 Pro Bowl selection trying to come back from an ankle injury last year, gained 29 yards on four carries.
Ryan, whose final month of '09 was affected by a turf toe injury, connected on a pair of third-and-long completions to tight end Tony Gonzalez, for 16 and 12 yards. He otherwise went 1 of 4 for 6 yards.
Cassel, who completed 6 of 8 passes for 25 yards, suffered from worse protection.
After a three-and-out, Cassel's second drive ended with Kroy Biermann's sack and John Abraham's fumble recovery.
Nine plays into his third drive, Cassel was sacked by middle linebacker Curtis Lofton for a 6-yard loss.
Lofton, the heart of Atlanta's defense, limped off the field before halftime, but Falcons officials said he only had a leg cramp.
McCluster, a second-round pick from Mississippi, ran five times for 25 yards and caught three passes for 22. He needed only limited space to run past the first level of Atlanta's defense and into the open field.
Chiefs kicker Ryan Succop twice tried field goals from 53, hitting the left upright and missing wide right. His 20-yarder with 2 seconds left before halftime made it 3-3.
Haley started Thomas Jones ahead of Jamaal Charles at running back. Jones played one series, gaining 2 yards, before Charles played the rest of the first quarter and into the second, running five times for 33 yards.
Croyle was 8 of 16 for 65 yards. Third-string Chiefs QB Tyler Palko completed 7 of 10 passes for 62 yards, but Falcons cornerback Chevis Jackson picked him off and ran the ball back 26 yards to set up Steve Hauschka's 37-yard field goal and a 20-3 lead.
Palko ran for a 1-yard TD in the final minute.
Hall helps Eagles to win
Wesleyan grad Chad Hall helped the Philadelphia Eagles to a 28-27 win over the Jacksonville Jaguars on Friday.
Hall caught a 57-yard pass from Mike Kafka to set up David Akers' game winning field goal in the fourth quarter.
Hall had two catches for 60 yards and made two rushes for 22 yards.
