Why a 49ers trade for Vikings receiver Jauan Jennings reportedly fell apart

Minnesota Vikings wide receiver Jauan Jennings (14) warms up before a game against the Saints in New Orleans on Oct. 11. (Tyler Kaufman/Associated Press) As it turns out, not every ex-player wants to reunite with the San Francisco 49ers.The 49ers worked out a trade last week for Vikings wide receiver Jauan Jennings, but the deal fell through because the seven-year veteran who spent his first six seasons with the franchise didn't want to return to Santa Clara, Fox's Jay Glazer reported.Jennings' decision came during a week in which the 49ers traded with the Colts for former defensive tackle DeForest Buckner, and months after they signed linebacker Dre Greenlaw and wide receiver Deebo Samuel, members of their 2019 draft class who returned to the 49ers after spending a season with the Broncos and Commanders, respectively.Meanwhile, the 49ers' deal with Minnesota was contingent on Jennings accepting the trade, but he reportedly declined to get on a FaceTime call with general manager John Lynch and head coach Kyle Shanahan.The report confirms the 49ers are in the market for a wide receiver before the Nov. 10 trade deadline. And it also strongly suggests Jennings left the 49ers with bruised feelings before he signed a one-year, $8 million contract with the Vikings in May.But that's not a huge surprise. Jennings requested a trade before the start of last year's training camp and questions were raised about the severity of a calf injury that sidelined him last summer as he unsuccessfully angled for a contract extension.The 49ers reached a compromise by adding $3 million in playing-time incentives to Jennings' deal. But there were signs of discord. Jennings engaged in a sideline screaming match with Shanahan during a Week 6 loss to Tampa Bay and afterward took the unusual step of detailing the specifics of the multiple injuries he was playing through to reporters.The Vikings (6-0) entered Week 8 as the NFL's only unbeaten team. Their willingness to trade Jennings to the 49ers (6-1), whom they could be battling for the NFC's No. 1 seed, reflects how they value their new addition. Jennings entered Week 8 with four catches for 43 yards while playing 234 snaps in five games.SubscribeThere’s more to San Francisco with the Chronicle.
