Yankey was the lone Bay Area representative on the first team, but Stanford linebacker Trent Murphy and receiver-returner Ty Montgomery were named second-team All-American and linebacker Shayne Skov earned a spot on the third team.
Yankey was part of an offensive line that ranks fourth nationally for fewest tackles for loss allowed per game (3.6) and 16th nationally for fewest sacks allowed per game (1.15).
The All-America teams were released Tuesday and selected by a panel of AP college football poll voters.
Other highlights of the All-American first team included Heisman Trophy winner Jameis Winston from Florida State at quarterback, running back Andre Williams from Boston College, Arizona running back Ka’Deem Carey and dual-threat quarterback Jordan Lynch from Northern Illinois as an all-purpose player.
