PITTSBURGH (AP) -- The Jacksonville Jaguars finally figured out how to win in Pittsburgh. The Steelers only wish they could.

Mark Brunell threw a short touchdown pass in the second quarter, and the Jaguars' stifling defense caused two safeties and outscored Pittsburgh's offense in a 17-3 victory Sunday.

Pittsburgh's bench at one point threw a white towel on the field to protest a call, but the Steelers offense probably should have tossed it as it was outscored 4-3 by Jacksonville's defense.

The Jaguars (3-1) won in Three Rivers Stadium for the first time in five games since joining the NFL and extended the Steelers' home losing streak to four -- their longest since a seven-game skid early in Chuck Noll's reign in 1969-70.

"Even last spring we talked about it. We had to come to our arch-rivals, in a place we've never won before, and win a game here before we could really be AFC Central champs," Jaguars coach Tom Coughlin said. "Hopefully, this will give us some momentum."

Coughlin also hopes it stops the talk about a feud with Brunell, who had a poor day statistically, going 10-for-25 for 85 yards. Coughlin reportedly screamed at Brunell for a last-minute interception in Jacksonville's 20-19 home loss to Tennessee last week.

Brunell again threw an interception into double coverage late in the first half, leading to Kris Brown's 48-yard field goal on the last play of the half for the Steelers' only points.

"That wasn't very smart, but we turned around and played great defense in the second half," Coughlin said. "I'm not frustrated at all, OK? We won the game, and we're going to enjoy it."

Added Brunell, "All I know is it feels great to finally win here."

GAME NOTES

Jaguars running back Fred Taylor reinjured his hamstring and sat out the second half. The same injury forced him to miss Jacksonville's loss to Tennessee last week. Jacksonville had been outscored 105-43 in its four previous trips to Pittsburgh. Kris Brown, Pittsburgh's rookie kicker, is 8-for-8 on field goals. This was the first time that neither Pittsburgh nor Jacksonville was in first place in the division when they met. Pittsburgh hadn't lost its first two home games in a season since 1986. The Steelers had never lost more than three in a row at home since moving into Three Rivers in 1970.

The Jaguars didn't dominate offensively as they did in beating San Francisco 41-3 in their opener, but they didn't need to against Pittsburgh's struggling offense. The Steelers (2-2) fell behind by 26 points last week in a 29-10 home loss to Seattle.

With the exception of a 43-0 season-opening rout of expansion Cleveland, quarterback Kordell Stewart has led the Steelers' offense to only two touchdowns in seven games dating back to last year.

"We're going to have to come in this week with a sense of urgency because this can't keep taking place every week," said Stewart, who was 15-for-32 for 126 yards and was twice pressured into safeties. "This can't keep happening."

The Jacksonville defense is thriving under former Steelers defensive coordinator Dom Capers. Pittsburgh, meanwhile, is struggling with the offense put together by former Jaguars coordinator Kevin Gilbride.

"Brand new or old, we can't keep doing this," Stewart said. "But I'm not going to beat myself up over this. I'm just not going to do it."

Jacksonville's defense twice stopped Pittsburgh on fourth-and-short plays in the second half, then scored a pair of safeties in the final five minutes.

Stewart was hit from the blind side by Tony Brackens and fumbled out of bounds for the first safety with 4:47 remaining, then was sacked again by Brackens in the end zone with 54 seconds remaining.

In a game dominated by defense, Coughlin's gamble resulted in the only touchdown.

Despite needing only inches on a fourth down from the Steelers 30, Jacksonville lined up for a field goal. But after a delay of game call moved the ball back to the 35, the Jaguars went for it on fourth-and-6 and Brunell scrambled 12 yards for the first down.

Three plays after Fred Taylor ran for 11 yards, Brunell found Keenan McCardell in the back of the end zone on a 7-yard scoring pass, only the third of the season by Brunell.

As it turned out, the Jaguars wouldn't need any more points, though Mike Hollis later made field goals of 27 and 41 yards.

The Steelers twice had chances to tie the score with Jacksonville leading 10-3 in the second half. But Stewart took off on a bootleg on a fourth-and-1 from midfield late in the third quarter and was dropped for a 5-yard loss. Later, Stewart threw incomplete into the end zone on a flea flicker on fourth-and-1 from the Jaguars 38.

"The fourth down calls were my calls," Steelers coach Bill Cowher said. "That goes on me."

Said Steelers offensive tackle Wayne Gandy, "It's a whole different game if we convert those plays."
