Isaac can be seen wearing his Magic game jersey instead.
He explained his stance on Friday before the game against the Brooklyn Nets, saying he didn't think "putting on that shirt and kneeling go hand in hand to support black life."
"For me, black lives are supported by the gospel. All lives are supported by the gospel, "he said. "We all have things that we do wrong and sometimes it gets to a point where we point out which finger is wrong is the worst. Or who is wrong is seen, then I feel like the Bible tells us that we are all short of the glory of God. It will help us get closer and go beyond the color of the skin.

We are committed to walking alongside our players - today and in the many days to come - in the search for lasting change and impactful. "
