Islanders’ Mike Reilly undergoing heart procedure after condition detected during concussion recovery

CALGARY, Alberta — Mike Reilly will undergo a procedure on Tuesday having to do with a heart issue that was uncovered during his recovery from a concussion, Isles general manager Lou Lamoriello said after the team practiced on Monday.

Reilly, who was knocked out cold by Jordan Greenway’s hit in Buffalo on Nov. 1, is out indefinitely but this is not considered to be a career-ending situation.

The 31-year-old has also recovered from the concussion that, in the moment, looked to be a potentially long-term issue.

“It’s something he’s had for a number of years that needs attention and he’ll be out indefinitely with it,” Lamoriello said of the heart issue, the specifics of which he declined to reveal. “… And it’s probably a blessing in disguise with what transpired that they detected this. Something that you’re sometimes born with but [he] never knew.”

Lamoriello said Reilly’s quality of life won’t be affected and the procedure is “in and out,” though it will take him “quite a bit of time” to return to play.

For the Islanders, that means Isaiah George’s stint with the team could be extended over the long term.
