Buxton was removed from his game Saturday with Triple-A Rochester due to a minor back issue, MLB.com's Rhett Bollinger reports.
It appears the Twins were just acting cautiously by pulling Buxton from the game, so it's not believed that the injury will dramatically delay his quest to return to the big leagues. He was hitting well with Rochester entering play Saturday, slashing .313/.368/.513 with three homers and two steals across 80 at-bats in the minors.
