Rockies closer Adam Ottavino will meet with the team's medical director on Monday, to learn the treatment plan for his triceps and elbow injury.
Ottavino is on the 15-day disabled list with an inflamed tricepts tendon, but an MRI last week showed the inflammation continues into the elbow, raising the concern that Tommy John surgery may be required.
"Nobody has said anything concretely about anything," Ottavino said, per MLB.com. "Until you are evaluated by a doctor … Those are the people who make those calls."
John Axford is filling in as closer. He has three saves and hasn't allowed a run, although with the Rockies in the midst of a five-game losing streak, he hasn't taken the mound since April 27.
