DETROIT -- Detroit center Henrik Zetterberg left the Red Wings' game Thursday night against Tampa Bay late in the first period because of an upper-body injury.
Zetterberg was helped off with 1:43 left in the period after taking a check from Mattias Ohlund. Zetterberg was on the ice on his hands and knees before being helped off.
The Red Wings won the game 3-0 behind Jimmy Howard's 30 saves.
Detroit coach Mike Babcock, who didn't know the extent of the injury or how long Zetterberg would be out, said the team's top point producer drove himself to the hospital to get an MRI after the game.
"That was unfortunate," Ohlund said. "I'm not trying to hurt anybody. I like to play hard."
Detroit is already without Johan Franzen, Valtteri Filppula, Jason Williams, Niklas Kronwall, Dan Cleary, Darren Helm and Jonathan Ericsson because of injuries. Despite those losses, they have won four straight.
Zetterberg has 10 goals and 22 assists in 34 games to lead the team in scoring.
