"We’re disappointed that he’s injured for him because he’s put so much work into it," Thibodeau told Johnson.
In the last four games D-Rose has missed because of his troublesome left big toe, Deng has averaged 19.5 points on 50 percent shooting with seven rebounds and three assists.
The South Sudanese baller has been having an All-Star-caliber season, averaging 15.9 points, 7.5 rebounds and 2.6 assists a night on 43.1 percent shooting.
Deng has provided the Bulls with a solid second offensive option for Rose by scoring 20 or more points in nine games in the young season.
Another aspect is Deng's stellar defense. He is a lockdown defender who contests shots and has the ability to steal the ball (over a steal a game in 2011-12) and turn that opportunity into easy fast-break points.
If Deng misses significant time, Thibodeau will likely go with backup swingman Ronnie Brewer as the starter and rookie Jimmy Butler could see an increased role off the bench.
Hopefully, Deng isn't seriously injured. If he is, the Bulls will have to try and win without their second-best player.
