Relating to immunity for ringside physicians assigned to combative sports events.

HB 5506 grants civil immunity to ringside physicians at Texas combative sports events (like boxing or MMA), protecting them from lawsuits for actions within their professional duties. The bill specifies this immunity applies only to ordinary negligence, not gross negligence by the physician. It does not cover lawsuits arising from reckless or willful misconduct. This law would take effect for cases filed after its implementation date, but does not change existing liability standards for gross negligence.
