Joshua was a healthy scratch for the first two games of the series but will replace Nathan Walker on the fourth line in Game 3. Joshua had three goals and five assists (eight points) in 30 games this season.
Patera was a sixth-round pick in 2017 and will serve as Logan Thompson's backup with Robin Lehner out for the final week of the season. Patera has gone 9-11-1 with a 2.89 GAA and .903 SV% in 21 games with Henderson this season.
Boeser missed the last five games with an upper-body injury but is set to play Monday vs. the Stars. Boeser has gone pointless in his last four games and has just 10 points (4G / 6A) in his 20 games.
Joshua, who has 17 points (7G / 10A) in 33 AHL games this season, will replace Alexei Toropchenko (lower-body) in the lineup on Saturday.
