LOS ANGELES -- Dodgers left fielder Alvin Toles will undergo an MRI exam on Wednesday to determine whether he damaged the anterior cruciate ligament in his right knee, manager Dave Roberts said after Tuesday night's 4-3 walk-off win over the Pirates.

Toles was injured chasing Andrew McCutchen's ground-rule double leading off the top of the seventh inning that broke up Dodgers starter Julio Urias' no-hitter. Just as the ball bounced into the box seats, Toles tried to pull up, but his knee buckled under him.

"X-rays look OK, but potentially might be a DL. We'll know more with an MRI tomorrow," said Roberts. "I didn't see the replay. As I heard, he was going up, trying to make a play on the ball and thought he didn't have room and came down on his right knee and it kind of gave way. Meniscus was fine. The only other possibility it could be is an ACL because of the way he landed, so we'll know more after the MRI."

Toles was replaced in left field by Enrique Hernandez, who one out later lost Francisco Cervelli's sinking liner in the lights and it rolled to the fence for an RBI double, with the run charged to Urias. Cervelli then scored on a flare single by Max Moroff, his first MLB hit.

Toles left the clubhouse before reporters were allowed in postgame and was unavailable for comment.
