Head coach Claude Julien confirmed the news following Monday's morning skate at the BB&T Center in Sunrise ahead of the matchup with the Panthers.
Weber, who is out with a lower-body injury, is also returning to Montreal for precautionary reasons, according to the Canadiens' bench boss.
"I'm a coach, not a doctor. I've been told that we're sending him back to Montreal as a precaution," said Julien. "Just like we've done over the last couple of weeks, we're making decisions based on the situations we're being forced to deal with. Things aren't urgent right now, so we're just taking precautions."
