Sources told me that Rose suffered a Grade 2 sprain of one of the
main ligaments on the outside of his ankle and it could affect his
mobility for Game 2 on Wednesday evening. He will be treated with
several different methods and is expected to start when the Bulls try to
even the series.
Here's the first random clip I found about grade 2 ankle sprain recovery times on google:
2: the ligament is partially torn with some resulting instability. Swelling
and bruising often occur immediately. A Grade 2 tear can take from 3-6 weeks
to heal and requires RICE therapy and rehabilitation exercises to strengthen
the ankle and ensure full range of motion of the ankle. If the ankle is
not rehabilitated properly, a Grade 2 sprain often leads to a weak ankle
with recurrent sprains.
That doesn't sound particularly good. Now Derrick is said to have no swelling which would indicate, possibly, a more minor sprain, but Derrick has looked obviously limited since his original sprain in game four.
He had little explosion in game two of the second round, and Atlanta gave him plenty of room to operate, but he still struggled to get things done. To me, this looks very similar to the start of his sophomore season where he had an ankle injury and started very slowly and looked like he wasn't playing with much burst.
I'm not panicked about whether the Bulls can beat the Hawks, but if Rose isn't healthy then there certainly should be an elevated level of concern. However, the Bulls simply aren't going to beat the Heat if Derrick Rose is playing on one wheel. Not unless something fairly extraordinary happens.
