The 49ers are reportedly giving up a third round draft pick in the deal.
Young has five sacks this year and was the 2020 NFL Defensive Rookie of the Year. He will be joining his old teammate Nick Bosa, the two played together at The Ohio State University.
The Niners are acquiring him at a time when the team has been stumbling. After firing off five straight wins to start the season, the 49ers have lost their last three.
The team has a bye this week. Their next game is Nov. 12 against the Jacksonville Jaguars.
The trade deadline for the NFL is Tuesday afternoon at 4 p.m. ET.
