This is the same injury that kept Lewis on the shelf from June 24-July 17 this season. He made only one start since returning from the DL before having to head back to the list.
Lewis, 32, is 6-6 with a 3.43 ERA, 1.08 WHIP and 93 strikeouts in 105 innings pitched this season.
As a corresponding move, left-handed pitcher Martin Perez has been recalled from Triple-A Round Rock.
Perez, 21, is 1-1 with a 5.54 ERA and 1.62 WHIP in four appearances for the Rangers this season. The highly-touted prospect is 5-5 with a 4.59 ERA and 1.39 WHIP in 86 1/3 Triple-A innings this season.
