Winnipeg Sea Bears center Chad Posthumus is in critical condition after undergoing surgery for a brain aneurysm, the team announced Thursday.

On Monday, the team said Posthumus suffered an aneurysm during a practice session and while he was in stable condition, he would need additional medical attention.

“Chad underwent a lengthy and complex surgery that successfully repaired a large brain aneurysm. Unfortunately, there were complications and he is now in critical condition in the intensive care unit,” the Sea Bears wrote in an article on X.

The team said their family appreciated the love and support they received during this time, but told them to give them their privacy.

“We continue to keep Chad and his family in our thoughts.”
