Wednesday games
Washington Capitals at Ottawa Senators (7 p.m. ET; RDS, SN, MNMT)
Brady Tkachuk has five points (four goals, one assist) and two goals in each of his past two games to help the Senators win two straight after losing their season opener. The Capitals are coming off the first win under coach Spencer Carbery and on the road for the first time this season. Nicklas Backstrom is expected to play his 1,100th NHL game and become one of six active skaters with at least 1,100 games and 1,000 points (Ovechkin, Sidney Crosby, Anze Kopitar, Claude Giroux and Joe Pavelski).
Pittsburgh Penguins at Detroit Red Wings (7:30 p.m. ET; MAX, TNT, TVAS)
A matchup of two premier defensemen with Penguins new acquisition Erik Karlsson against Red Wings defenseman Moritz Seider, a 22-year-old with three points (one goal, two assists) in three games and first in the NHL with an average of 23:47 in time on ice. Karlsson has one assist in three games after getting 101 points (25 goals, 76 assists) in 82 games last season to win the Norris Trophy voted as the best defenseman in the NHL. The game also could be Jeff Petry's first for the Red Wings against the Penguins since he was traded to the Montreal Canadiens in the three-team deal that sent Karlsson to Pittsburgh on Aug. 6. The defenseman was then traded to Detroit by Montreal on Aug. 15. His father, Dan Petry, played nine seasons for the Detroit Tigers, won the 1984 World Series and is a Tigers studio analyst.
