Weber was sent back to Montreal to be evaluated and won't play at the Florida Panthers on Monday (7:30 p.m. ET; FS-F, SNE, RDS, NHL.TV) or at the Buffalo Sabres on Wednesday.
"I'm a coach and not a doctor," Julien said. "I've been told as a precaution we're going to send him [back to Montreal]. We're not in an emergency situation and we're taking precautions."
The Canadiens, who have four games left, can clinch first place in the Atlantic Division with a win against the Panthers in any fashion Monday. They also can clinch if they get one point against the Panthers and the Toronto Maple Leafs lose to the Sabres (7 p.m. ET; NHLN, SN, TVA Sports, MSG-B, NHL.TV) in any fashion and the Ottawa Senators lose to the Detroit Red Wings (7 p.m. ET; FS-D, RDS2, TSN5, NHL.TV) in any fashion, or if the Maple Leafs and Senators each lose in regulation.
"It's a challenge, but it's not a bad challenge at this stage because we want to be able to evaluate our other players also in certain situations and it's going to allow us to do just that," Julien said.
Weber is tied for second among NHL defensemen with 17 goals, and has 42 points and is plus-20 in 78 games. This will be the first game Weber has missed this season.
