Dustin Pedroia left his rehab game Friday night because of discomfort, and the Boston Red Sox are bringing him back to the city for the team's medical staff to look at his ailing left knee on Monday.
He had two at-bats for Double-A Portland Friday before he pulled himself out of the game.
The second baseman, 35, has played in just nine games for the Red Sox in the 2018 and 2019 seasons.
"I mean, it's another red flag, so we talked a little last night," Red Sox manager Alex Cora told reporters. "We talked this morning. He just didn't feel right yesterday. He's not going to push it. He's not going to make it worse. Yesterday he didn't feel right so decided to stop playing."
Pedroia last played for the Red Sox on April 17 against the New York Yankees but felt a pop in his knee during that game. He played one week in Portland earlier this month but also ended that rehab stint because of discomfort.
Pedroia underwent cartilage restoration surgery on his left knee in October 2017 with the hopes that lingering knee discomfort would go away. He was expected to miss the first few months of the 2018 season, but he played in just three games. This season, he has appeared in six games, with two hits in 20 at-bats.
Pedroia was named the American League Rookie of the Year in 2007 and the Most Valuable Player the following season. He is a .299 career hitter with 394 doubles, 140 home runs and 725 RBIs.
