CHENEY, Wash. (AP) — The Seattle Seahawks have wrapped up their training camp at Eastern Washington University and now head into their third preseason game Friday night in San Diego.

Seahawks break camp in Cheney; Dilfer to play Friday

Once back from southern California, the team will spend the rest of the preseason practicing at team headquarters in the Seattle suburb of Kirkland.

Before leaving Wednesday, head coach Mike Holmgren announced that backup quarterback Trent Dilfer will make his preseason debut against the Chargers. Dilfer sat out Seattle's first two preseason games with back spasms, but returned to practice earlier this week.

Dilfer will play most of the second half in San Diego. Holmgren said he expects most of his starters to play most of the first half.

Dilfer was acquired by the Seahawks before the 2001 season, after leading Baltimore to the Super Bowl title in 2000. Dilfer has started 10 games with Seattle and has a 6-4 record.

SNAP DECISION: The Seahawks are remarkably consistent when it comes to PATs.

Seattle has converted every extra-point attempt in 146 consecutive regular season games, dating back almost 10 years.

That's 331 attempts since Dec. 11, 1994 — an NFL record.

For the last 152 tries, Canadian Jean-Philippe Darche has been responsible for the snaps. Darche gets paid $535,000 a year to bend over and fire footballs between his legs as Seattle's long snapper.

”It's a good lifestyle,” said Darche, a Montreal native who signed with the Seahawks in 2000.

Darche grew up dreaming of playing for the Montreal Canadiens and said he'd still rather play in the NHL. His younger brother Mathieu is a left-winger for the Colorado Avalanche.

But Darche fell in love with football in high school. He played at McGill University, then completed two years of medical school before signing in 1999 with the Toronto Argonauts of the Canadian Football League as a long snapper and backup linebacker.

”I just wanted to do it for one year,” Darche said. ”I didn't even know I was that good.”

SUCCESSFUL SURGERY: Outside linebacker Chad Brown underwent successful surgery on his broken left leg Wednesday, the team said.

Team doctors Kevin Auld and Ed Khalfayan performed the surgery on Brown's left fibula at the Seattle Surgery Center.

Brown broke the lower leg bone in practice Monday when his feet got tangled with tight end Itula Mili during a passing drill. Brown is expected to miss the first four games of the regular season.

LINEBACKER BATTLE: The race for the starting role at middle linebacker will take another turn Friday when rookie Niko Koutouvides will get the start.

Koutouvides has been locked in an even battle with fourth-year pro Orlando Huff and second-year player Solomon Bates for the starting spot. Huff started Seattle's preseason opener against Green Bay and Bates got the nod last week against Denver.

Koutouvides was a fourth-round draft pick out of Purdue.
