Allard was recalled from Triple-A Round Rock on Monday, Levi Weaver of The Athletic reports.
Allard spent several days with the Rangers prior to being sent down Sunday, but he didn't make any appearances during his stint in the big leagues. He'll rejoin the major-league bullpen after Dane Dunning (ankle) was placed on the 15-day injured list Monday. Over seven relief appearances for the Rangers this year, Allard has posted a 5.06 ERA and 1.06 WHIP in 16 innings.
