ST. LOUIS -- Blues defenseman Torey Krug injured his right foot while training for the coming NHL season, general manager Doug Armstrong announced Tuesday.

The Blues did not reveal how long they expect the 32-year-old to be sidelined, other than to say Krug is expected to be reevaluated Oct. 1.

St. Louis opens the season Oct. 12 at Dallas. Krug's injury is a pre-training camp blow to the organization that's attempting to return to the playoffs quickly after a rare down season and trading away Stanley Cup-winning forwards Vladimir Tarasenko and Ryan O'Reilly.

Krug is going into his fourth season with the Blues since signing a seven-year, $45.5 million contract in 2020. The former Boston Bruins defenseman has 112 points in 185 regular-season and playoff games with St. Louis.

If Krug misses time early in the season, it would create a spot for one of the Blues' young defensemen, either Tyler Tucker or Scott Perunovich, to get a regular role on a blue line that includes veterans Colton Parayko, Justin Faulk, Marco Scandella, Nick Leddy and Robert Bortuzzo.
