The Rockets suspended first-round pick Royce White for ‘‘refusing to provide services’’ required by his contract on Sunday. General manager Daryl Morey said that the team will continue to work with White in hopes of finding a resolution. White, who will not be paid during his suspension, refused his assignment to Houston’s D-League affiliate last week. The 16th overall pick in the draft has spent most of the season on the inactive list while he and the team figure out how to handle his anxiety disorder and overall mental health. White has been vocal on Twitter during this saga, and he continued to voice his opinions after the announcement. ‘‘What’s suspending me supposed to do. I’ve been away from the team for a month 1/2. Guess we want to give it a title to shift accountability,’’ he tweeted. That was the first in a string of tweets on the subject. He then addressed Morey. ‘‘Threat, Fines, Suspension won’t deter me. I won’t accept illogical health decisions, I will keep asking for safety & health. #BeWell @dmorey,’’ he tweeted . . . Guard Daequan Cook, cut by the Rockets on Thursday, signed with the Bulls . . .
