Toronto Blue Jays outfielder George Springer has undergone an MRI after feeling quad tightness while running the bases during a live batting practice on Tuesday.
Blue Jays manager Charlie Montoyo says the team is still gathering information about the injury.
Springer was taking live batting practice as part of his rehab from a Grade 2 oblique strain that landed him on the injured list to start the Blue Jays season.
The 31-year-old is eligible to return to the team on Thursday, but this latest injury could delay his Blue Jays debut once again.
