Mikolas received a platelet-rich plasma injection for his sore flexor tendon Tuesday, Derrick Goold of the St. Louis Post-Dispatch reports. He's expected to rest for around a month before ramping up his throwing program.

EDGE Analysis

Mikolas will likely continue to take part in fielding and cardio work while he waits for the shot to take effect, but the delayed start to his throwing program looks like it will prevent him from being ready for the March 26 season opener at Cincinnati. Even if he gets the green light to resume pitching by mid-March, Mikolas would likely need at least a couple weeks to build up to a starter's workload before the Cardinals would break him into the rotation. Assuming Mikolas is moved to the injured list to begin the campaign, spots in the rotation could open up for both Carlos Martinez and Kwang-Hyun Kim.
