Mikolas received a platelet-rich plasma injection Tuesday morning into his right arm and around the ailing flexor tendon. He has been prescribed rest for the next three to four weeks. He will be able to participate during the non-throwing drills of spring training. He will be evaluated in mid-March to determine if he can begin a throwing program and use the minor-league spring training to ramp up to be ready to join the rotation at some point, possibly in late April.
