Nicholas Brendon is recovering after suffering a "cardiac incident" earlier this month.
The Buffy the Vampire Slayer actor's sister shared an update on Brendan's condition on her Instagram page, revealing she had to be taken to the emergency room.
Nikki sent her love and wanted me to apologize she hasn't been going live lately and to give everyone an update," the post began.
Some of you may remember that a similar incident happened last year (for cauda equina) after his second spinal surgery," she continued.
Brendon suffers from Cauda Equina syndrome, which is when the nerve roots in the lumbar spine are compressed, limiting movement and sensation.
