Wallinder inked a two-year, two-way contract with Detroit on Thursday.
Wallinder is coming off his third straight campaign with AHL Grand Rapids, having notched two goals and 18 helpers in 66 regular-season games with the Griffins. Selected by the organization with the 32nd overall pick in the 2020 NHL Draft, Wallinder is never going to produce at Moritz Seider levels, but he could be in line to make his NHL debut this year.
