The Wolves' issues with their second unit just got more complicated: Derrick Williams will not play tonight against Dallas at Target Center because of back spasms.

Williams' absence takes away scoring from a second unit that already is struggling in that area. Backup center Ronny Turiaf is out injured, shooting guard Alexey Shved hasn't played well at all so far and other teams are hounding J.J. Barea because he's the best -- and maybe now only real -- scoring option for the reserves.

Let's see if tonight is the night you finally get a good look at Robbie Hummel or Shabazz Muhammad in something more than clean-up time.
