The Grizzlies did not practice today but forwards Darrell Arthur and Zach Randolph received treatment for their respective injuries. Both players are listed as day-to-day but questionable for Wednesday's home game against the Portland Trail Blazers. Arthur continues to suffer from back and neck soreness after a nasty fall in the second quarter of the Grizzlies' win at Orlando on Sunday. The team's medical staff has completely ruled out a concussion after further evaluation. Arthur landed on his back and then his head hit the court. Randolph remains hobbled by a left ankle sprain he suffered Friday in a loss at Miami. Randolph didn't play Sunday at Orlando.
