Yakovlev (upper body) won't be in the lineup against Vancouver on Friday, Amanda Stein of the Devils' official site reports.
Yakovlev will miss his second game due to his upper-body issue. The defender struggled for a spot in the lineup earlier in the year and may be hard-pressed to secure minutes down the stretch, especially once Sami Vatanen (illness) and Mirco Mueller (shoulder) are cleared to return.
