After dropping its first three Classic 8 Conference games, Muskego's path to playoff eligibility was clear.
Needing to win its final four games, the Warriors saw their hopes at a late-season run to the postseason dashed in a 38-29 loss to Kettle Moraine on Sept. 23.
Muskego will miss the playoffs for the first time since 2013 and for just the second time in the past seven seasons.
The Warriors (2-4, 0-4 Classic 8) started fast against the Lasers, taking a 7-0 lead on a 38-yard touchdown pass from sophomore quarterback A.J. Makinen to Alex Kalisnig on the first play of their second drive.
On the ensuing possession, Kettle Moraine thought it was third down when it really was fourth down. Muskego took over on the Lasers' 6-yard line after an unsportsmanlike conduct penalty. Justin Kotarek found the end zone on the next play to put the Warriors up, 14-0.
Kettle Moraine (3-3, 2-2) scored late in the first quarter and midway through the second to pull even and took the lead on a 14-yard touchdown pass from Max Duchow to Sam DeLany with just four seconds left in the first half.
A 6-yard touchdown run by Mike Timm gave the Lasers a 28-14 advantage with 6:43 to play in the third quarter.
Kotarek pulled Muskego to within 28-21 with a 17-yard touchdown with 4:53 left in the third, but Kettle Moraine scored 10 unanswered points to build a 38-21 lead with 4:11 to play.
Michael Madia rattled off a 50-yard touchdown run, and Muskego converted the 2-point conversion with 11 seconds left, but it was too late for a Warrior comeback.
Muskego will look to snap its four-game losing streak when it hosts winless Waukesha South at 7 p.m. Friday, Sept. 30.
The Blackshirts (0-6, 0-4) have lost their four conference games by an average of 36.5 points.
