Norris (lower back) will not be ready for the beginning of the regular season, Jason Beck of MLB.com reports.
After having his start moved back from Saturday to Tuesday, Norris gave up three runs over just one-third of an inning and appeared to be in discomfort while leaving the field. Even if the tightness in his back subsides within the next few days, the lefty won't be stretched out enough to make a start during the first week of the season, as he's only around 50 pitches. Shane Greene, Matt Boyd and Buck Farmer are now the candidates to fill Detroit's final rotation spot. Norris won't necessarily have the job once he's healthy, having allowed seven runs over just 6.1 innings this spring.
