I think from a perspective of competing and also maximizing our opportunities to assess players and who might not stick around I would do the following moves:
Send Beck down
Call-up Roy (who would have gotten the call instead of Beck first time around if he wasn't hurt apparently) or Farrell
Put Newhook at C
That way you can see how Newhook does at C as Dvo's potential replacement and you can also evaluate Roy or Farrell before potentially dealing them this summer for a 2C. Roy IIRC had chemistry with Newhook.
