Toronto Maple Leafs goaltender Jean-Sebastien Giguere will miss at least one week of action, the team announced on Wednesday.

General manager Brian Burke said the injury timetable due to Giguere's groin injury could be as much as two weeks.

Netminder James Reimer has been called up from the American Hockey League. Reimer will back up Jonas Gustavsson when Toronto hosts New Jersey on Thursday.

Gustavsson was pressed into service in the third period of Tuesday's game against Nashville when Giguere went down, with the Leafs clinging to a 5-4 lead. Gustavsson stopped all six shots he faced in 13 minutes of action as Toronto won for the first time in nine games.

Toronto plays six games over the next two weeks.
