Seattle Seahawks quarterback Geno Smith is the real deal according to head coach Pete Carroll after he kept them into first place in the NFC West with their third straight win on Sunday.

Smith threw two touchdowns, completing 23 of 34 passes for 212 yards with no turnovers, in the Seahawks' 27-13 victory over the New York Giants on Sunday. He should have had a third TD pass if not for a Tyler Lockett drop on a would-be score.

The 32-year-old Seahawks quarterback has been a revelation this season, having spent the past seven years primarily as a back-up, before taking over from Russell Wilson after his trade to the Denver Broncos.

Smith has already this year matched his career-best 13 touchdown passes in a single season from 2014, with nine games remaining.

"He's the real deal, we're seeing it," Carroll told reporters. "There's no mystery or, 'Oh, he's going to run out of gas or something.' It's not like that.

"He knows exactly what he's doing and he shows you week in, week out, throw after throw after throw. There's nothing for us to hold him but in the highest of expectations, really.

"What a thrilling story for the kid. He just hung in there so tough and outlasted it and now he's enjoying all the fun of it. He did great."

Smith has completed 181 of 249 attempts with a 72.7 completion rate for 1,924 yards with three interceptions this season.

The Seattle QB has also rushed for 158 yards with one touchdown, but would not get caught up in the universal praise coming for him as the surprise of he season.

"Man, we just got a win today," Smith said. "We only got a chance to play one game today, and we won it.

"We've got to continue to play hard throughout the season. Every single game is going to be a test. We know that.

"We always talk about each game being a championship opportunity and so we're just going to continue to focus on it day by day, not get caught up in the outside noise - and just do what we do."

The Seahawks are top of the NFC West with a 5-3 record, ahead of the San Francisco 49ers (4-4) and the Los Angeles Rams (3-4) and the Arizona Cardinals (3-5).

The Seattle Seahawks are hoping to have DK Metcalf and Tyler Lockett – their leading two pass-catchers – available against the New York Giants on Sunday.

The Week 8 matchup pits two of the NFL's surprise packages against one another, with the Giants 6-1 in the NFC East as the Seahawks lead the NFC West at 4-3 despite trading quarterback Russell Wilson.

Seattle have received a boost ahead of welcoming the Giants to Lumen Field, as both Metcalf and Lockett could feature.

Metcalf was carted off in last week's win against the Los Angeles Chargers with a patellar tendon injury, prompting fears he could miss an extended period.

But the wide receiver avoided surgery, and ESPN's Adam Schefter reported he would face the Giants, while NFL Network's Ian Rapoport said he has "a good chance".

Metcalf has caught only two touchdown passes this season after a career-high 12 last year, although his 418 receiving yards rank in the league's top 25.

He trails team-mate Lockett, who has 468 yards and two TDs and also should play on Sunday.

Lockett has been managing both hamstring and rib injuries, but Schefter expects him to play. Rapoport described him as "a game-time decision" but with "some optimism he goes".

Elsewhere in the NFL, early reporting on Sunday had Las Vegas Raiders receiver Davante Adams and Dallas Cowboys pass rusher Micah Parsons both on course to play despite previously being listed as questionable.

Adams, whose Raiders go to the New Orleans Saints, was ill, while Parsons has been dealing with a shoulder injury ahead of the Cowboys hosting the Chicago Bears.
