Swisher was on the DL for 15 days in late May and early June with a hyperextended left knee; this time he is dealing with soreness in his right knee. The team also said Swisher has a minor injury to his right wrist.
The Indians signed Murphy, 32, as a free agent in November and he has hit .262/.324/.384 in 109 games this season, with 36 runs, 21 doubles, seven home runs and 55 RBI.
Swisher, 33, has had a disastrous season. In 97 games, he is hitting just .208/.278/.331 (all career lows) with 33 runs, 20 doubles, eight homers and 42 RBI to go with 111 strikeouts.
Holt, 25, was a 10th-round pick of the Indians in 2010 out of Florida State and made his major league debut last month, getting two plate appearances and going 0-for-1. He was also hit by a pitch.
Holt leaped through the top two levels of the minors this season, hitting .298/.416/.347 with 11 stolen bases in 39 games for Double-A Akron and .311/.420/.405 with 20 thefts in 58 games at Columbus.
Cleveland acquired Walters from the Washington Nationals on July 31 in the deal that sent shortstop Asdrubal Cabrera to D.C.
Walters, 24, had played in 32 games for the Nationals, hitting .205/.279/.462 with three homers and five RBI.
He hit .300/.358/.608 at Triple-A Syracuse while still in the Washington organization, with 15 homers and 48 RBI.
Since the trade, he was 12-for-31 with two homers and eight RBI in seven games with Columbus.
