The Yankees are back to full strength now.
Aroldis Chapman will be activated off the disabled list before Wednesday's game against the Red Sox, the Yankees announced.
The left-handed closer had been in the DL since Aug.22 with left knee tendinitis.
Chapman is the second Yankee to come off the DL in a week. Aaron Judge was activated Friday night after missing 45 games with a fractured right wrist. He was cleared to hit in a game and returned to the starting lineup Tuesday night.
Chapman has 31 saves and a 2.11 ERA in 50 appearances this season.
