The Maple Leafs will recall rookie netminder Dennis Hildeby for the second time this season ahead of Tuesday’s game against the Blues, TSN’s Mark Masters reports. Backup Martin Jones is unavailable with an undisclosed injury after missing Monday’s practice.

That means Toronto needs to clear two roster spots in the next few hours — one to allow them to temporarily carry three goalies, and one to activate center David Kämpf off injured reserve. Head coach Sheldon Keefe confirmed Tuesday morning that Kämpf will return against St. Louis after missing three games with an undisclosed injury (via Masters).

To do so, the Maple Leafs will likely place defenseman Conor Timmins on injured reserve and return Maxime Lajoie to AHL Toronto from his emergency loan. Timmins, 25, is out indefinitely with mono, Keefe said Tuesday.

The 22-year-old Hildeby spent nine days on the Maple Leafs roster last month with Joseph Woll sidelined with a high ankle sprain and starter Ilya Samsonov on a short-term AHL assignment after a difficult start to the season. The 6-foot-7, 223-pound Swede is having a strong first professional season in North America, logging a .913 save percentage and four shutouts in 24 AHL games, although he’s yet to make his NHL debut.

Jones, 34, stopped 27 of 31 shots faced in a 5-3 loss to the Senators on Saturday, ending a run of five straight starts for Samsonov. A pair of underwhelming showings now has Jones’ save percentage on the year down to .908, although it’s still his best in six years. He’s started 16 games and made two relief appearances for Toronto this year in a third-string role behind the inconsistent Samsonov and the injured Woll, posting a 9-7-1 record and two shutouts.
