Sokol was claimed off waivers by the Patriots on Wednesday, Chris Mason of MassLive.com reports.
Sokol signed a reserve/future contract with the Lions in January, but he ultimately was cut last Tuesday. The 26-year-old last played in the NFL with the Chargers in 2020, appearing in two games. He'll likely compete with the duo of 2020 third-round selections Devin Asiasi and Dalton Keene for a roster spot.
