Beauvillier, a first-round pick (No. 28) at the 2015 NHL Draft, has one goal in four games this season.
Beauvillier hasn't played since a 3-2 loss at the Anaheim Ducks on Oct. 11. He will replace forward Joshua Ho-Sang, who was benched for most of the third period and did not play in overtime of the Islanders' 4-3 shootout win at the New York Rangers on Thursday.
The Sharks will play their second game in as many nights following a 3-0 win at the New Jersey Devils on Friday. It's the second of a five-game road trip for San Jose, which played its first five games of the season at home.
It's also the second time in eight days the Sharks and Islanders will play against each other; New York won 3-1 at SAP Center on Oct. 14.
