Ketel Marte is returning to Phoenix for an MRI on his knee, per Steve Gilbert of MLB.com, after the Arizona Diamondbacks placed the second baseman on the restricted list.

The MRI adds a medical dimension to what had already been a developing situation. Earlier items from the Posterior newsroom noted that Marte failed to appear at Fenway Park for a game against the Red Sox, with the restricted list move coming just before first pitch in Boston. Now, with a knee MRI in the picture, the full scope of his absence remains unconfirmed.

What we know

Marte has been placed on the restricted list by Arizona and is traveling back to Phoenix to undergo the MRI. Per Steve Gilbert's report, the Arizona coaching staff is keeping its focus on the ongoing series in Boston.

What remains unconfirmed

The results of the MRI have not been reported. No timetable, diagnosis, or return date appears in the material. Whether the knee concern is connected to his absence from Fenway is not stated in the source.

The Diamondbacks have not issued a prognosis, and the nature of the restricted list placement has not been formally clarified in the material. The restricted list can be used in a range of circumstances; the MRI news does not resolve which category applies here.

Watch for MRI results out of Phoenix and any corresponding roster or lineup moves as the D-backs continue their road series.
