The Commercial Appeal's Ron Tillery is reporting via Twitter that the back injury that Zach Randolph sustained during Wednesday night's game against the San Antonio Spurs is going to keep him from playing tonight:

Zach Randolph missed shootaround today (lower back strain) and will not play tonight

So there's that. Randolph is day-to-day with his back, so hopefully he'll be ready to go against the Indiana Pacers on Monday.

My guess would be to look for Marreese Speights or Darrell Arthur to get the start in Randolph's place tonight.
