Sonny Milano scored with 2:58 remaining in the third, setting up overtime where Alex Ovechkin won it with his 790th career goal in a 3-2 loss to the Capitals that sent the Flyers streak to eight games.
It was an ugly game for the Flyers, who trailed 3-1 after the first and lost Carter Hart and Cam Atkinson for the night before allowing six more goals over the final two periods in a 9-2 drubbing to the Washington Capitals.
The Capitals have a lot to play for, looking to claim an edge in the East Division race. Just like earlier this week against Pittsburgh, the Flyers look to play spoiler, starting with Friday night's opener.
The Flyers should have plenty of motivation to continue their positive play from Thursday, beings that Saturday afternoon's opponent handed them another embarrassing defeat earlier this week. The Washington Capitals are back at Wells Fargo Center for another matchup.
The Flyers face the Washington Capitals one day after the two teams were trade partners on deadline day. Michael Raffl will not play Tuesday, but newcomer Anthony Mantha will be in the lineup for Washington.
