KANSAS CITY, Mo.(AP) -- The greatest offensive line in the world
couldn't have protected Eli Manning from this injury.

All the New York Giants quarterback did was drop back to pass,
something he's done how many thousands of times?

Suddenly, he felt pain in his right heel. He stayed in for one
more play, a short pass to Hakeem Nicks which the rookie turned
into a beauty of a 54-yard touchdown play in a 27-16 victory
over Kansas City.

But now Manning and the Giants will have to wait and see if a
worrisome bruised right heel will let him play next Sunday
against Oakland.

"It was a noncontact. It just happened into the drop," said
Manning, who threw for 292 yards and three touchdowns as the
Giants (4-0) won their third road game in a row. "It was the
play before the touchdown, where I had Steve Smith deep and
threw it a little short."

Manning was replaced by David Carr, but said he expects to be
ready for the next game.

"I always assume I'm going to play, that I'm going to be out
there," he said. "I've always been a pretty quick healer. I'll
be doing everything I can possibly do this week to get healthy
and prepared to play Oakland. We'll find out more tomorrow. I
can walk around and move around, but there is some discomfort."

Manning threw threw two scoring passes to Smith, who totaled 134
yards on 11 catches, as the Chiefs (0-4) lost for the 27th time
in 29 games.

"We've got to stick together as a team, which I think our guys
are doing very well," said Chiefs coach Todd Haley. "We've got
to pull together and start becoming a team much like that team
across the field from us today."

In the final minutes, Matt Cassel threw two short scoring passes
that made the final score unreflective of how badly the Giants
outplayed their hapless hosts.

From the first quarter, when Jamaal Charles fumbled the opening
kickoff and Manning converted it into a quick TD, this battle
between occupants of opposite ends of the NFL standings never
seemed in doubt. After going 0 for 11 in third-down conversions
the week before against Philadelphia, the Chiefs were 2 for 15.

"Change is not fun," said Haley. "We've got to be better in all
areas."

The Chiefs have lost their first four games for the first time
since 1980.

A 15-yard unnecessary roughness penalty on safety Jarrad Page
for a hit on Smith helped put the Giants in position for their
second TD, Manning's 25-yard pass to Smith.

Lawrence Tynes, a former Chief, kicked field goals of 25 and 40
yards for New York.

Bryan Kehl, who recovered Charles' fumble of the opening
kickoff, was again in the right spot when the Chiefs tried an
onside kick to open the second half. He pounced on the ball and
a few minutes later, Tynes' 40-yarder put the Giants on top 20-3
with 10:22 left in the third quarter.

Ryan Succop kicked a 33-yard field goal in the first quarter for
the Chiefs, but that was the end of their scoring until Cassel's
1-yard scoring pass to Sean Ryan late in the fourth quarter.
With 4:54 left, Cassel tossed a 2-yard TD pass to Bobby Wade.

Brandon Jacobs had 92 yards on 21 carries for the Giants, who
rolled up 429 yards while holding the Chiefs to 193.

Giants coach Tom Coughlin said Manning could not have stayed in
the game.

"Not at that point. He didn't leave the bench, so I'm sure
whatever is going to be done is going to be here from here on
out," Coughlin said. "I think he's going to be sore. I really
don't know a whole more than that."

Notes: Chiefs are in the middle of a four-week section through
the NFC East, with Dallas and Washington to go. ... Giants' two
first-quarter turnovers were their first in three games. ...
Giants and Seattle are the only teams to play three straight on
the road this year.
