Rice has big half, Seahawks defence stuffs Rams in 24-7 victory

ST. LOUIS - The Seattle Seahawks opened the game with a 55-yard trick play followed by an interception by Tarvaris Jackson.

No matter. A defence led by Chris Clemons made sure they didn't need too much scoring to put away the St. Louis Rams.

Wide receiver Sidney Rice completed a 55-yard pass to open the game, caught a touchdown pass and drew a pass interference call to set up a field goal as the Seahawks beat the Rams 24-7 on Sunday.

Clemons had three of Seattle's five sacks on Sam Bradford and also forced the Rams quarterback to fumble twice, both of which led to touchdowns.

Marshawn Lynch scored for the fourth straight week, although he missed on a third straight 100-yard game, finishing with 88 yards on 27 carries . The Rams (2-8) totalled 185 yards.

The Seahawks (4-6) won on consecutive weeks for the first time, following up on an upset over Baltimore, and have won 12 of 13 in the series.

Seattle improved to 2-4 on the road in a game notable for sloppy play and 19 punts, including a season-high 10 by the Rams' Donnie Jones.

Lynch scored on a 3-yard run in the third quarter, five plays after Bradford fumbled at the St. Louis 25, and Justin Forsett broke several tackles on a 22-yarder on third-and-11 to clinch it with 4:21 to go. The clincher came three plays after Red Bryant intercepted a pass tipped at the line by Brandon Mebane.

Running behind an injury-riddled line, St. Louis' Steven Jackson had 42 yards on 15 carries to end a run of three straight games of 125 or more yards.

The Rams opened without starting tackles with Rodger Saffold (pectoral) and Jason Smith (concussion). Practice squad callup Kevin Hughes was called on to play after fill-in tackle Mark Levoir injured his right shoulder in the first half.

With under seven minutes to go in the first quarter, the Rams had two interceptions, a blocked punt and their first touchdown in the opening quarter since Jackson scored on a 47-yard run on St. Louis' first offensive snap of the season against the Eagles.

After that, they couldn't get going. A defence that totalled four sacks kept it close for a while, but the Rams never made it to the red zone and crossed the 50 only three times.

Seattle took a 10-7 lead on Steven Hauschka's 19-yard field goal to end the half, one play after Justin King was called for interference in the end zone against Rice.

Rice executed a flea-flicker on the game's first play, hitting Mike Williams in stride with a step on King for a 55-yard gain to the Rams 30. On the next play, Jackson was intercepted by Chris Chamberlain.

The Rams didn't cash in on that turnover, but Quintin Mikell's pick on the Seahawks' next series set up Brandon Lloyd's 30-yard touchdown catch. Lloyd fell down on his route and then sprang to his feet to catch cornerback Richard Sherman by surprise.

Rice made his second big play on a 14-yard catch that tied it 7-all midway through the second quarter.

The Rams' 10 first-down snaps in the half produced minus-2 yards.
