TORONTO (AP) Toronto Blue Jays reliever Brett Cecil tore his left calf muscle during Friday's AL Division Series game and might be done for the postseason.

Cecil, Toronto's top left-hander in the bullpen, was injured while tagging Mike Napoli in a rundown that ended the eighth inning of a 6-4 loss to the Texas Rangers. He had to be helped off the field.

Toronto manager John Gibbons said Cecil has a ''pretty significant tear in his calf, so that's not very good.''

Gibbons said left-hander Aaron Loup will have to step up.

Toronto is down 0-2 in in the best-of-five ALDS.
