Washington played with nine forwards for most of the game against Detroit.
Oshie was injured after he checked Red Wings center Riley Sheahan 8:10 into the game.
Oshie, 29, has 12 points (eight goals, four assists) in 17 games this season. He has 373 points (144 goals, 229 assists) in 540 NHL games during nine seasons with the St. Louis Blues and Capitals.
Capitals forward Lars Eller is day to day with an upper-body injury that occurred on his first shift of the game Friday. Eller has two goals in 17 games this season, his first with Washington, which acquired him from the Montreal Canadiens in a trade for two draft picks on June 24.
Trotz said Eller will not play against Columbus Blue Jackets on Sunday (12:30 p.m. ET; SN, CSN-DC, FS-O).
Forward Andre Burakovsky also left in the first period on Friday but participated in practice Saturday and could play against Columbus.
"He's obviously skating with us," Trotz said. "It'll just be a game-time decision. All things are trending that he looks pretty good."
The Capitals called up forward Paul Carey from Hershey of the American Hockey League on Saturday.
Trotz ruled out going with 11 forwards and seven defensemen for the third game of a five-game homestand, saying he didn't want to overuse his top lines.
"I mean from a forward standpoint, when you're leaning on forwards, you can actually use your higher-end guys a little more," Trotz said. "I thought about it, but we don't have to and I don't necessarily want to."
