Update (11:17 PM): I was wrong about Holmstrom.
Bruce MacLeod reports that Kris Draper is a “maybe” for Wednesday, while neither Tomas Holmstrom nor Darren McCarty are expected to be ready. Downey, however, is able to return.
If Draper (or Holmstrom or McCarty) is not able to make it back, the team will recall Mattias Ritola or Darren Helm.
According to Griffinshockey.com, the Wings have returned Mattias Ritola and Darren Helm to Grand Rapids.
As pointed out by George Malik, that should mean two of the following will be back Wednesday night: Aaron Downey (flu), Tomas Holmstrom (abdominal/groin), Kris Draper (groin tear), and Darren McCarty (ribs).
My guess? It'll be Downey (who should be over his flu) and Holmstrom (whose injury seemed less severe than Draper's). That would make the forward corps look like this:
Of course, that's just speculation. It's also possible that McCarty could make his return debut at the expense of Downey, though I'd be surprised if Draper plays.
