Upton is slated to have an MRI on his left big toe Monday, Mike DiGiovanna of the Los Angeles Time reports.
Upton was diagnosed with a sprained left big toe after colliding with the fence in left field during Sunday's spring game, and although is X-rays came back negative, he'll undergo an MRI to rule out further injury after his toe wasn't any better Monday, per DiGiovanna. Upton's status for Opening Day will likely hinge on his MRI results.
