The point guard, who missed all of last season while recovering from ACL surgery, featured in the team's first two games of the pre-season, but sat out in Rio de Janeiro at the weekend.
The 25-year-old, who practised fully on Monday, told ESPN: "My knee was good. I never was worried about it. I could have played but the front office made a decision to sit me out. My health is the number one [concern].
"I'm fine with [people asking], man. It's just something I've got to deal with. Does it get irritating? Sometimes, but I had the injury, and it's something all of us have to go through.
"Going into [the process], you hear about it, but when it actually happened, it surprised everyone. Like I said, I could have played in the game but they made a decision and I just listened to them."
Rose is expected to play against the Detroit Pistons later today.
