Maple Leafs' goaltender Vesa Toskala has been complaining of a sore groin for some time, and sources tell TSN it was really bothering him during the team's 7-3 win over Pittsburgh on Saturday.
The 31-year-old is expected to return to Toronto on Sunday as he needs a couple of days to rest.
In response, Toronto recalled goalie Justin Pogge from the Toronto Marlies of the American Hockey League on Sunday. The team's next game is in Atlanta against the Thrashers on Monday.
Pogge was the Maple Leafs' first pick in the 2004 NHL Entry Draft, going in the third round, 90th overall. He is 10-9-3 with a 2.86 GAA and an .890 save percentage for the Marlies this season.
The 22-year-old has appeared in 111 AHL games in his career.
The Maple Leafs called Pogge up on January 11, 2008, but he saw no playing time before being reassigned to the Marlies the following day.
Toskala, meanwhile, was not very busy against the Penguins on Saturday, facing only 23 shots. He has played 29 games this season and has been in goal for all of Toronto's 13 wins. He has a 3.11 GAA and .887 save percentage.
