The Bulls' official Twitter account confirmed that Rose had a torn meniscus and that there was no timetable for his return, reporting that he is out indefinitely.
While the Bulls won't give a specific time for when Rose will return, Dr. Mark Adickes said on the video from ESPN below that Rose could miss as much as four to six months or as little as two to six weeks.
Before the injury, Rose had played in 10 games and was putting up 15.9 points, 4.3 assists and 3.2 rebounds per game. However, he was shooting just 35.4 percent from the field, and he was working on getting more comfortable on the court.
The Bulls had been adjusting to the fact that Rose was trying to get back into the flow of the game after coming off of a torn ACL, and it felt like the team was starting to get into a groove. They scored 110 points against the Indiana Pacers and gave them their only loss this season.
Now, the Bulls will have to adjust once again, with Kirk Hinrich now having to run the offense.
At 32 years old, Hinrich is starting to slow down. He's averaging 27.9 minutes per game this season, but he's only putting up 8.3 points and 4.5 assists per game while shooting 38.2 percent.
Hinrich is going to have to play major minutes, because the Bulls don't have the most appealing options to play point guard behind him. Marquis Teague would be the other option, and he's shooting just 30.8 percent and has a player efficiency rating (PER) of negative-2.0. Mike James is another option, but he's played just three total minutes this season and has yet to take a shot.
Other key players will have to pick up the slack quite a bit in order to keep things moving.
As a team, the Bulls are 25th in the NBA in scoring, averaging just 93.5 points per game. The point guard position is key to an effective offense, and having to trust Hinrich or Teague certainly isn't promising.
Carlos Boozer will have to score even more in these upcoming games. He's currently averaging 16.2 points per game while shooting 51.7 percent, so he's been efficient, but he will need to start taking over 15 shots per game to help his team out.
In the weak Eastern Conference, the Bulls shouldn't have a problem making the playoffs. However, if Rose comes back late in the season, the Bulls will have to adjust once again, and that will keep this team from having much success in the postseason.
Getting timing down is important for a team, and without Rose, the Bulls have to get on the same page as the team adjusts to their star player's absence.
