The San Francisco 49ers made a huge move to address their struggling defense with a trade for edge rusher Chase Young, and they aren't necessarily done yet.

San Francisco agreed a 2024 third-rounder to the Washington Commanders in exchange for former second overall pick Young in a deal pending a physical.

The Niners had been reported to be interested in trading for a cornerback as well as an edge rusher, and San Francisco could yet pull off another deal for the 4 p.m. ET deadline.

Tim Kawakami of The Athletic reported the 49ers are closing in on another trade, though he did not identify the player in question.

San Francisco, per multiple reports, was said to be one of the teams interested in acquiring Chicago Bears cornerback Jaylon Johnson. However, after being given permission to seek a trade, Johnson is reportedly set to stay in Chicago..

Cornerback has emerged as a huge problem area for the 49ers, with slot corner Isaiah Oliver coming in for significant criticism after a porous performance in Sunday's loss to the Cincinnati Bengals.

If the Niners do make a deal, it would likely be to shore up that spot with defensive coordinator Steve Wilks under mounting pressure after three successive defeats.
