The Vikings activated Herndon (illness) from the reserve/COVID-19 list Friday.
Herndon is healthy for the offseason after missing Week 18. He played in each of Minnesota's first 16 games in 2021, but was targeted only five times while averaging 11.5 snaps per contest. Herndon turns 26 in February, and 60 percent of his career receiving yards (502 of 836) came during his 2018 rookie campaign. He'll become an unrestricted free agent in March if he doesn't re-sign with Minnesota first.
