The Montreal Canadiens have acquired goaltender Jake Allen and a 2022 seventh-round pick from the St. Louis Blues in exchange for third- and seventh-round picks in the 2020 NHL Draft.

Allen posted a 12-6-3 record with a 2.15 goals-against average and a .927 save percentage in 24 regular-season games with the Blues. In five games during the NHL's Return to Play, Allen posted a 2-1-1 record with a 1.89 GAA and a .935 save percentage.

The 30-year-old is a veteran of 289 NHL games, posting a career record of 148-94-26 with a 2.50 GAA and a .915 save percentage.

Allen is signed through next season at a cap hit of $4.35 million.

Blues general manager Doug Armstrong said Ville Husso will serve as Jordan Binnington's backup next season. 

"With the flat cap next year and probably moving forward, we wanted to create some space for this (off-season)," Armstrong said. "Also, I think jointly with that, is trying to incorporate younger players into our group. Ville Husso is a player we've had high hopes for and we believe has earned the right to compete for an NHL job. To do that, you need to create opportunity."

Husso, a fourth-round pick of the Blues in 2014, had a 16-17-8 record with .909 save percentage and a 2.56 goals-against average with the AHL's San Antonio Rampage this past season. The 25-year-old has never appeared in an NHL game.

Both picks traded by the Canadiens were previously acquired in separate trades. The third-round pick was acquired from the Washington Capitals, while the seventh-rounder was acquired from Chicago.
