Bradley, 27, was placed on the 10-day disabled list on Aug. 23 with a sprained left thumb suffered while sliding awkwardly into home plate to avoid a tag. He was expected to be in Saturday's lineup at Yankee Stadium.
In 107 games for the Red Sox this season, Bradley is batting .262 with 14 home runs, 54 RBIs and 50 runs scored, while posting a .992 fielding percentage with four assists in 106 starts in center field.
In seven games prior to suffering the thumb injury, Bradley went 8-for-20 (.400) with nine RBIs, hitting a solo home run in his most recent game on Aug. 22 at Cleveland. Bradley has appeared in 501 major league games since being selected by Boston in the 2011 draft, hitting .243 with 54 home runs, 224 RBIs and 250 runs scored.
The Red Sox also recalled infielder Tzu-Wei Lin from Triple-A Pawtucket.
Lin, 23, is batting .280 (14-for-50) with two triples and a .379 on-base percentage in 19 major league games this season, making six starts each at third base and shortstop and two at second base.
A native of Taiwan, Lin had never played above the Double-A level prior to being selected to the major league roster on June 24. He is hitting .266 in 82 minor league games this season, his first 48 with Double-A Portland and his final 34 for Pawtucket. He was signed by Boston as an international free agent in 2012.
