Zylstra caught one of two targets for 23 yards in 16 games this season.
Zylstra also returned one kick for 15 yards and returned four punts for 26 yards as he saw more than one offensive snap in only three games in 2018. The former CFL wide receiver will look to gain an increased offensive role in 2019 as the Vikings received little production at wide receiver behind top targets Stefon Diggs and Adam Thielen.
Zylstra (undisclosed) is active for Sunday's game against the Patriots.
Zylstra was initially listed as questionable for Sunday's tilt against the Patriots, but will ultimately suit up without issue. He's expected to take most of his snaps on special teams.
Zylstra is listed as questionable for Sunday's Week 13 game against the Patriots with an undisclosed injury, Andrew Krammer of the Minneapolis Star Tribune reports.
Zylstra has been handed the questionable tag, but he isn't actually listed with an injury. The 25-year-old has played eight offensive snaps this season, so the Vikings offense is unlikely to impacted by the 25-year-old's uncertainty for Sunday.
