Dustin Pedroia is back on the shelf again.

The Red Sox officially placed the second baseman on the 10-day Injured List Thursday night, 24 hours after he left Wednesday’s 5-3 loss to the Yankees with a sore knee.

According to Peter Abraham of The Boston Globe, the Red Sox initially feared Pedroia sustained a major injury, but now believe he can return from the Injured List sometime in May.

“The Sox feared a serious injury [when Pedroia left Wednesday’s game] but now believe Pedroia will be able to continue playing,” Abraham wrote.

This marks the latest setback in Pedroia’s attempt to rehab from cartilage restoration surgery in his knee after the 2017 season. He played just three games in 2018 before he was shut down for the rest of the season, and appeared in six games this year before landing on the IL again.

Pedroia could not play in the field on back-to-back days and played in only three minor league rehab games for Single-A Greenville before the Red Sox activated him for the home opener at Fenway Park last week.

The 35-year-old Pedroia is 2-for-20 this season.

The move to call-up Walden means the Red Sox currently have only 11 position players on their roster. Presumably, the team will call up an infielder in the near future, likely Tzu-Wei Lin, who cannot be recalled officially until Friday after he was sent down to Pawtucket on April 9.
