Luol Deng will miss tonight's game against the Portland Trail Blazers with a hamstring injury in his left leg.

Deng tweaked the area during Tuesday's shootaround before the Bulls played the Lakers in Los Angeles. He then further aggravated the injury during the game while scoring nine points in 26 minutes.

Without Deng in the starting lineup, coach Vinny Del Negro decided to go with a three-guard lineup with Larry Hughes joining Ben Gordon and Derrick Rose in the lineup. Drew Gooden starts at power forward and Aaron Gray takes over for the struggling Joakim Noah at center.
