With Lars Eller out, the Washington Capitals will suit up with 11 forwards and seven defensemen against the Buffalo Sabres at KeyBank Center on Monday night.

Trevor van Riemsdyk will be the the team’s seventh defenseman, but it’s unclear if he will get The Jonas Siegenthaler Treatment or not. The game will mark van Riemsdyk’s eighth as a Capital since signing over the offseason.

Lars Eller (lower body, day to day) will not play tonight vs BUF. Caps will go with 11F/7D, per Laviolette.

TvR will dress as the 7th D.

van Riemsdyk is suiting up for Eller who injured himself in the first period of the Capitals’ 5-4 victory over the Philadelphia Flyers on Friday. The Capitals are classifying Eller’s injury as “day-to-day.”

It appears this is where Lars Eller got injured. He was racing back for a loose puck and then kinda pulled up lame, lifting his right leg. pic.twitter.com/8NJzb76sy4

Meanwhile, Vitek Vanecek will get his first start since March 9 – a 5-4 overtime victory over the New Jersey Devils. Vanecek had given up eight goals in his last two starts.
