Top prospect Roberto Osuna was tapped to start in place of Estrada. It was Osuna's first official start of the Grapefruit League season, after previously drawing rave reviews for his work out of the bullpen.
Estrada technically is competing for the final spot in the rotation, but the job all but officially belongs to rookie left-hander Daniel Norris. Estrada will instead begin the year in the bullpen as a possible long reliever and swingman.
The 31-year-old becomes the second Blue Jays pitcher this spring to sustain an injury during fielding drills. Right-hander Marcus Stroman tore his ACL during bunting practice and will miss the entire 2015 season.
Toronto has experienced a lot of trouble staying healthy this spring, with almost half of its 25-man roster coming down with at least minor ailments in camp. In addition to Estrada and Stroman, there have been eight other players affected by injuries.
The list includes: Michael Saunders (knee), Kevin Pillar (oblique), Edwin Encarnacion (back), Ramon Santiago (collarbone), Brett Cecil (shoulder), Maicer Izturis (groin), Dioner Navarro (knee) and Jose Bautista (hamstring).
