The routine at the Raptors practice facility was disrupted slightly for a good cause yesterday.In addition to those players taking advantage of the one-on-one gym time the team is offering, the facility was playing host to voluntary antibodies testing open to players, coaches and staff. It’s part of a Mayo clinic study the NBA has joined. Teams, at least the teams with their own practice facilities open, have the opportunity to undergo the testing which will confirm first whether you have already had the virus and then if antibodies are present in your blood.
