The club announced the move Wednesday.
In his place, rookie Steve Mason came up from the minors and won all three games he started. Mason was named the NHL's No. 2 star for last week.
The 26-year-old Leclaire has gone 3-3-0 with a 3.41 goals-against average and 0.885 save percentage in seven games this season. He has a 44-52-11 record with a 2.75 goals-against average and 0.910 save percentage in 120 career NHL games.
