Mason tweaked the knee during the Jets morning skate before their 3-2 win at the New Jersey Devils two days later and was sent back to Winnipeg to be evaluated.
Goaltender Michael Hutchinson was called up from Manitoba of the American Hockey League on March 8 and will back up Connor Hellebuyck when the Jets face the Washington Capitals at Capital One Arena on Monday (7 p.m. ET; TVAS, NBCSWA, TSN3, NHL.TV).
Maurice said Hutchinson, 2-0-0 with a 2.00 GAA and .933 save percentage with the Jets this season, will start against the Nashville Predators in the final game of the Jets' six-game road trip on Tuesday.
Mason, 29, signed a two-year contract with the Jets as an unrestricted free agent on July 1, 2017. This season, he is 4-6-1 with a 3.18 goals-against average, a .906 save percentage and one shutout.
Center Mark Scheifele will miss his third consecutive game Monday because of an upper-body injury, but participated in the Jets morning skate wearing a yellow non-contact jersey.
Maurice said Scheifele also won't play at Nashville.
"He's not in full contract, so he's not ready to play," Maurice said. "But we do not want a reoccurrence, so we'll be real patient with this one."
Scheifele, who has 51 points (21 goals, 30 assists) in 50 games this season, missed 16 games from Dec. 27 to Feb. 9. with an upper-body injury. The Jets said his current injury is not related to the previous one.
The Jets (41-18-9) are in second place in the Central Division, seven points behind the first-place Predators and six ahead of the third-place Minnesota Wild. They are 3-1-0 so far on their road trip.
