What happened: The Minnesota Vikings and San Francisco 49ers reached an agreement on a trade to send wide receiver Jauan Jennings back to the Bay Area, but the transaction collapsed after Jennings expressed that he did not want to return. Jennings joined Minnesota on a one-year contract in the offseason after spending his first six seasons with San Francisco.

Why it matters: The 6-0 Vikings have continued assessing depth options as the Vikings explore trade market moves across their offense ahead of the deadline. San Francisco, standing at 6-1, sought veteran pass-catching help following its first defeat of the season.

What to watch: Both teams have until the NFL trade deadline on Nov. 10 at 4 p.m. ET to pursue further roster adjustments.
