Dumba (lower body) won't need surgery but is considered week-to-week, Brian Rea of Bally Sports Southwest reports Tuesday.
With Dumba on the shelf, the team called up Alex Petrovic from the minors in order to bolster its defensive depth. Still, it's Nils Lundkvist who figures to see the biggest uptick in ice time without Dumba on the blue line. Given his recovery timeline, Dumba will likely wind up on injured reserve sooner rather than later.
