MIAMI -- Backup quarterback Matt Moore rallied Miami two fourth-quarter touchdowns and the Dolphins edged the Dallas Cowboys 25-19 on Saturday night.

Running back Orleans Darkwa capped a 12-play, 55-yard drive by plowing into the end zone for the decisive score with 1:45 left in the game.

Moore, who went 12-for-19 for 173 yards and one touchdown, hooked up with Harold Hoskins at the 5:40 mark of the fourth quarter for a 27 yard touchdown.

Dallas quarterback Tony Romo played the first half and was sacked three times. Coming off surgery to repair his back, Romo completed 10 of 18 passes for 87 yards.

"It was good to see Tony out there playing," Dallas coach Jason Garrett said at halftime. "He got knocked around a little bit, and that could be good and bad. It's good to have him feel the physical part of the game."

Miami starting quarterback Ryan Tannehill completed 13 of 21 passes for 119 yards as he played into the third quarter before giving way to Moore.

Dallas rookie Tyler Patmon's nine-yard interception return for a touchdown midway through the fourth quarter put Dallas up 20-11. But there was plenty of time left for Moore's heroics.

Knowshon Moreno, who played with the Denver Broncos last season, made his preseason debut for the Dolphins. The first time he touched the ball he ran for 19 yards. He finished with 64 yards on 10 carries.

Rams 33, Browns 14

Cleveland -- Quarterback Sam Bradford "dodged a bullet" during St. Louis' dominating win over Cleveland. Bradford left the game midway through the first quarter clutching his left knee, the same knee he had surgery on last year to repair a torn ACL.

After the game, multiple outlets reported that tests showed the ACL was not injured. He will have an MRI on Sunday. Third-string quarterback Austin Davis threw for 198 yards and two touchdowns.

The Browns mustered just 100 yards of offense in the first half and ended the game with a grand total of 197 yards. Starting quarterback Brian Hoyer threw for one score and rookie backup Johnny Manziel ran for a score. Rams rookie Michael Sam sacked Manziel twice and mimicked the Browns rookie by making Manziel's "money" sign.

Titans 24, Falcons 17

Atlanta -- It didn't take long for quarterback Matt Ryan and the Falcons offense to put on a show, but in the end it was the Titans who walked away with a victory.

Ryan completed 18 of 23 passes for 224 yards and two touchdowns for a 136.2 passer rating. For good measure, Ryan also rushed for six yards. Wide receiver Julio Jones also showed he has recovered from a devastating foot injury that curtaled his 2013 season. Jones bobbed and weaved through the Tennessee defense on his way to a 52-yard score in the second quarter.

But the Titans scored 10 unanswered fourth-quarter points, highlighted by rookie Bishop Sankey's three-yard TD run with 5:45 to go in the game that was the difference. Sankey was the workhorse for the Titans as they look to replace former Pro Bowl running back Chris Johnson who now plays for the New York Jets. Sankey rushed 16 times for 44 yards and the game-winning score.

Ravens 23, Redskins 17

BALTIMORE -- Quarterback Joe Flacco found a diving Steve Smith for a 24-yard touchdown in the closing seconds of the first half, and the Baltimore starters outplayed the Washington Redskins.

Washington's first team offense could not find any continuity and struggled to move the ball. Quarterback Robert Griffin III dealt with a furious pass rush. He completed 5 of 8 passes for 20 yards and was sacked three times.

Meanwhile, Flacco appears to have a full grasp of the playbook by new offensive coordinator Gary Kubiak. Flacco was 16 of 23 for 180 yards and the touchdown. Smith had seven catches for 80 yards and the touchdown, which gave Baltimore a 10-3 lead with 25 seconds left in the first half.

Buccaneers 27, Bills 14

Buffalo, N.Y. -- Tampa Bay jumped out to a 24-0 lead behind quarterback Josh McCown and running back Doug Martin, and never looked back.

Martin opened up the scoring with a one-yard plunge in the first quarter and McCown tossed a scoring strike to rookie wide receiver Mike Evans near the end of the first half as the Buccaneers dominated a struggling Bills squad.

In between those scores, defensive tackle Clinton McDonald recovered a fumble by Bills' second-year QB EJ Manuel and rumbled 17 yards for a defensive score.

Manuel played three quarters and finished 19-for-28 and 198 yards with one touchdown and an interception. McCown finished 13 of 16 for 112 yards with one touchdown and one interception. Buffalo was playing without rookie wide receiver Sammy Watkins, who was out with a bruised leg.
