The Cubs activated Swanson (oblique) from the 10-day injured list Friday, Meghan Montemurro of the Chicago Tribune reports.
He had been sidelined since mid-August with a Grade 2 left oblique strain. Swanson did not go out on a rehab assignment, but he participated in a simulated game at Wrigley Field earlier this week to clear the path for his return. He will take back over at shortstop for the Cubs, with Nico Hoerner returning to his familiar second base.
