Syndergaard was placed on the 15-day injured list Thursday with a blister on his right index finger, Bill Shaikin of the Los Angeles Times reports.
Syndergaard has dealt with a blister problem off and on for the last month or so and also cracked a fingernail during Wednesday's outing versus the Reds. He'll be eligible to return later this month, but this could offer an opportunity for a reset for the struggling right-hander. With Julio Urias (hamstring) due back soon, Syndergaard's place in the rotation may have been tenuous regardless of the finger issues.
