Vlasic (undisclosed) took part in pregame warmups and will be active for Wednesday's game against the Senators, Curtis Pashelka of Bay Area News Group reports.
EDGE Analysis
Vlasic was held out of Tuesday's 3-2 win over the Maple Leafs with the mystery ailment but it appears it was nothing serious as he'll return to action after missing just one game. While the 29-year-old blueliner has been averaging top-six minutes all season, he hasn't tallied a point since Nov. 19 and only has seven on the campaign, which makes him a poor play in most fantasy formats.
