After missing four games with an undisclosed “upper-body” injury, forward T.J. Oshie will return to the lineup on Saturday against the Philadelphia Flyers on Saturday night. “Everything feels good right now,” Oshie said. “As long as somehow something bad doesn’t happen on the way home, I think I should be good to go.” It was in a game against the Flyers that Oshie absorbed several big hits that knocked him out for more than a week. He said this injury is unrelated to the shoulder injury he had earlier this season, and while Oshie was pushing to play sooner, Washington’s staff opted for caution with the team in a comfortable position in the standings. Oshie is expected to skate as the top-line right wing with center Nicklas Backstrom and left wing Alex Ovechkin. Oshie, who has 24 goals and 19 assists in 50 games this season, also plays on the top power-play unit, and Saturday’s game will be the first time seeing the power play with both Oshie and newly acquired defenseman Kevin Shattenkirk there. Oshie and Shattenkirk were teammates in St. Louis.
