ST. LOUIS — Returning to Scottrade Center might always feel “a little awkward” for T.J. Oshie after he played the first seven seasons of his career here with the Blues. But when Oshie saw that the Capitals‘ annual mentors’ trip would include a game in St. Louis, he was overjoyed to be able to bring his father, Tim Oshie, or “Coach,” back to the city they both grew to love.

“I was excited for Coach,” T.J. Oshie said. “He might have more friends in this town than I do. So, it’s good for him to come back and see some familiar faces. I think it’s special for him to be back here.”

Tim Oshie has had Alzheimer’s disease since 2012, so the Capitals allowed T.J. to also bring his father-in-law, Dave Cosgrove, on the trip to ease some of T.J.’s worries about Tim.

“It’s a real first-class organization,” T.J. Oshie said. “It’s real family-oriented from [Coach Barry] Trotz to [General Manager Brian MacLellan]. I couldn’t be more thankful. With my dad, sometimes he just needs a little extra help. It takes away the worry for me when I’m here that he’s taken care of by father-in-law Dave. So, it’s great that both of them are allowed to come. And Dave’s having a blast, so it’ll be good.”

Oshie said he had dinner with some former teammates on Wednesday night, going over to Barret Jackman’s home with his father and Cosgrove. Blues players Ryan Reaves, Jaden Schwartz and Patrik Berglund were also there. When St. Louis players spotted Tim Oshie as they came off the ice after their morning skate, several called out to him and said hello.

“A lot of those guys on the other side know Coach pretty well,” Oshie said. “I think it’s more meaningful for him to be able to come back here and see me play.”

>>> This trip may consist of mostly players’ dads, but Trotz wanted to make sure the moms got appropriate credit even though they’re not traveling with the team this weekend.

“I’m going to put a lot of heat on the dads to make sure they send a gift home the next day,” Trotz said. “That’s going to be part of my meeting [on Thursday] with the dads is they better get online, order something, bring something back, take mom out for a high-end dinner when they get home, massage her feet, whatever it takes because I don’t bring them on the trip. But they’re very important, too.”

>>> Defenseman John Carlson will miss a second straight game, out against the Blues because of an undisclosed lower-body injury. Carlson didn’t skate Thursday morning and the team has Friday off, so it would reason that Carlson is doubtful to play in Dallas on Saturday night. Trotz didn’t commit to that, and he said skating on Saturday morning could be enough for Carlson to play.

“We’ll see where that is,” Trotz said. “We don’t know. We’ll just know what we know. . . . He’s doing his therapy and he’s doing his rehab, so we’ll see when he’s ready and then we’ll put him back in.”

Here’s what the Capitals’ lineup will look like on Thursday night:

Alex Ovechkin-Nicklas Backstrom-T. J. Oshie

Daniel Winnik-Jay Beagle-Tom Wilson
