An MRI revealed that Los Angeles Dodgers outfielder Yasiel Puig has a strained left-thumb ligament, Manager Don Mattingly said after his team’s 6-2 win over the San Francisco Giants on Sunday.

Mattingly added that he thought Puig’s injury would be more of “day-to-day thing” instead of a situation that would require Puig being sent to the disabled list. The 23-year-old was held out of Sunday’s game and left the clubhouse early to have the MRI on his sore left thumb.

Puig hurt himself sliding headfirst into first base in the third inning on Saturday but was able to finish out the game, which the Dodgers (5-3) lost 7-2 to the Giants (5-2). The X-rays done on the thumb after the game came back negative.

“We’ll know a lot more not necessarily from the results, but just how he feels [Monday] and as the strength comes back in there,” Mattingly said (via ESPN).

Puig could return to the lineup as early as Tuesday night when the Dodgers start their two-game series against the Detroit Tigers.
