The CanElson Drilling Estevan Bruins snapped a seven-game point streak on Monday in Weyburn, losing 4-1 in their first meeting this season against the Red Wings.
They had beaten the Notre Dame Hounds 4-2 in Wilcox on Saturday, their sixth win in seven games.
The Bruins (9-6-2-1) are in third place in the Viterra Division and fourth in the SJHL.
Estevan had plenty of power play opportunities on Monday, including a four-minute advantage with a lengthy 5-on-3 to start the third period, but they went just 1-for-10 with the man advantage.
"It would've been totally different (had we taken advantage)," said Bruins head coach and general manager Chris Lewgood. "You have to work hard on the power play and outwork your opponents and when you lose the battles, it makes it hard to succeed on the power play, and that's what happened to us."
Former Red Wing Austin Roesslein scored the Bruins' lone goal, coming at 14:36 of the first period on a power play. That gave them a 1-0 lead after one.
Ty McLean tied it for the Wings eight minutes into the second, and Ryan Cooper scored to put them ahead with less than two minutes to play in the period.
The Bruins were still in it until, with less than six minutes left, Kyle Oleniuk and Brian Farkas scored 20 seconds apart on power plays.
Newly acquired defenceman Tanner Clark had taken hooking and unsportsmanlike conduct penalties to put Weyburn on an extended power play.
"Those are the ones that kill you, when you take undisciplined penalties. The boys rally around you when it's the hard, physical ones, but when you're taking selfish ones, it's a little harder to kill them off," Lewgood said.
"We just didn't come to play. In the SJHL, there's so much parity that if you take a day off, you're probably going to lose and that was our fate."
The Wings outshot the Bruins 36-32, with Matt Gibney in goal for Estevan and Rylan Parenteau in net for Weyburn.
The Bruins had points in seven straight games before the Weyburn loss, and Lewgood stressed that it was one bad game, not "a series of bad events."
On Saturday, the Bruins took the lead early and never let it go against the Hounds, a former division rival.
"The boys worked hard. I thought for the most part the effort was there. It took us a bit to get organized on the big ice," Lewgood said.
Lynnden Pastachak opened the scoring just shy of the 10-minute mark of the first period.
Hudson Morrison added to the lead six minutes into the second on a power play.
Hounds forward Devin McGonigal got his team in the game at 10:15 of the period, but Austin Daae's ninth goal of the year on a power play less than two minutes later put the Bruins ahead by two.
Spencer Trapp scored at the 16:25 mark with another power play marker to get the Hounds within a goal after 40 minutes.
Wyatt Garagan's tally halfway through the third made it 4-2.
The Hounds outshot the Bruins 30-23.
"I felt we had a lot of quality chances," said Lewgood. "We were able to bury the puck when we had chances."
It was Clark's first game as a Bruin after being acquired from the OCN Blizzard earlier in the month, and he had one assist.
"He adds a great element to the power play. He's very comfortable on the point," Lewgood said of the new defenceman.
The Bruins' next game is on Friday when they host the Nipawin Hawks. They also face the Melville Millionaires at home on Tuesday. Both games start at 7:30 p.m. at Affinity Place.
