Casey Dornbach scored his second goal of Sunday's matinee late, but ultimately the Lincoln Stars fell 4-3 in overtime to Dubuque at the Ice Box.
It took all of 18 seconds for the Saints' Quinn Preston to score in the extra session and give Dubuque the victory.
Despite the loss, Lincoln picked up three points in three games over the weekend and now trails Sioux City by two points in the Western Conference standings for the final playoff spot.
"We looked tired and it manifested more in our mental game then anything," Lincoln coach Cody Chupp said. "It's just tough; we made some mental errors that were costly, and I thought we were sloppy and sluggish through most of it."
The Stars were coming off back-to-back games that they split with Omaha on Friday and Saturday before Sunday's contest with the Saints.
“There were spurts of decent hockey,” Chupp added. “To get out of this one with a point, when we go back and watch the video, we are going to be happy that we got a point."
After a Josiah Slavin short-handed and game-tying goal was waved off, Dornbach and the Stars found themselves on just their second power play of the afternoon.
Dornbach picked up a pass from Eero Teravainen in the right slot just outside the faceoff circle and fired it past a screened Cole Weaver in the Dubuque net.
“It was a test of the resiliency of this group and just stuck with it whether we were getting calls or not,” Dornbach said. “It's been going on; we just have to play our game and I thought we did a good job bouncing back, but obviously a tough result.”
Derek Schaedig suffered the loss in net, stopping 24-of-28 shots. It was his first start for the Stars since Jan. 21.
“Obviously not playing for awhile, it takes a bit to get back into it and be feeling good and confident,” Schaedig said. “I just tried to go out there and get the jitters out in the first 10 minutes or so. Being fresh helps when the boys' legs are hurting a little bit, so I thought I helped in that way.”
Devlin McCabe added his 10th goal of the season in the second period to tie the game again 2-2, after Dubuque scored at the buzzer to end the first period 2-1.
Dornbach added his 16th goal of the season and first of the afternoon in the first period after former Lincoln Star Chayse Primeau gave the Saints a 1-0 lead on the power play.
Chupp noted the team will have an off day to regroup after a three-game set and return to the Ice Box on Friday against the Fargo Force.
