Gsellman experienced back tightness after tossing a scoreless inning Friday against the Cardinals, Justin Toscano of The Bergen Record reports.
Gsellman threw 20 pitches in the seventh inning and complained of back tightness after the frame, which is why he wasn't sent back out to handle the eighth. He'll be considered day-to-day moving forward.
