Yes it's true and this news will confirm it http://sportsillustrated.com.ph/US/nba/2017/10/20/derrick-rose-injury-news-update-cavaliers and also this mate confirms it
I don't think these injuries isn't just an accident because it's consecutively happening for each match, though it's normal for each match that there will be some injuries during matches but it's quite odd.
Thanks for confirming, this is quite odd. A lot of things are happening with this, they are playing with their full force so in return to that friction when something wrong happened that results to a severe injury.
