Hernandez has right triceps tendinitis, Todd Zolecki of MLB.com reports.

EDGE Analysis

It had previously been reported that Hernandez may have been dealing with an elbow issue, but the current diagnosis appears more minor and the club is deeming it just a day-to-day situation. If that's the case, the team's likely closer should be ready to go for Opening Day if he's able to get back on the field without missing extended time.
