The San Francisco 49ers traded a 2015 fourth-round draft pick to the Buffalo Bills to acquire wide receiver Stevie Johnson.
It's a conditional pick that could become a third-rounder, according to ESPN.
“Stevie was a great contributor during his career with our organization,” Bills general manager Doug Whaley said in a statement. “Today’s decision was not an easy one to make, especially involving a player like Stevie who leaves everything he has on the field and is an emotional leader in our locker room. All of the decisions we make are done so in the best interest of our team.
"We wish him the best of luck in San Francisco and throughout the rest of his NFL career. We also want to thank Stevie and his family for their commitment to the Buffalo Bills and the community over the last six years.”
Johnson caught 52 passes for 597 yards and three touchdowns in a dozen games last season as he battled back,groin and hamstring problems.
Johnson averaged 79 receptions and had three consecutive 1,000-yard seasons between 2010 and 2012.
Johnson is a San Francisco native.
He joins a receiving corps that already includes Anquan Boldin and Michael Crabtree.
