SEATTLE, DEC. 24 -- The Seahawks need help to get into the playoffs, so the players don't even worry about the various possibilities.

"You just got to go out and play," Seahawks quarterback Dave Krieg said Sunday night after Seattle's 17-12 win over Denver. "You can't think about all the ramifications because a lot of things can happen."

Seattle (8-7) can make the playoffs in two scenarios. In the first, the Seahawks must beat Detroit (6-9) at home next Sunday and hope Pittsburgh beats Houston or Cleveland beats Cincinnati.

If the Seahawks lose to Detroit, they could make it in if Cincinnati and Houston lose.

The end of Sunday's game was no less confusing. John Elway threw an apparent 51-yard touchdown pass to Michael Young, but it was nullified by an illegal motion penalty on Denver wide receivers Young and Shannon Sharpe.

"That game was typical of the whole year," said Denver Coach Dan Reeves, who has watched his club go from the Super Bowl to 4-11 in 11 months.

Seattle started off the season 0-3, but is 8-4 since despite injuries to its starting linebackers. Dave Ahrens broke his right fibula in the first quarter Sunday night and his backup, Ricky Andrews, tore the rotator cuff in his right shoulder. Linebackers Terry Wooden, Rufus Porter and Darren Comeaux all are finished for the year with injuries.
