Kelly exited Game 5 of the NLCS against Atlanta on Thursday with shoulder stiffness, Fabian Ardaya of The Athletic reports.
Kelly threw 28 pitches as the team's opener and managed only two outs prior to exiting with the apparent injury. He also wasn't particularly effective while on the mound, as he allowed a two-run home run to Freddie Freeman -- the third batter batter of the contest. There is no timeline for Kelly's potential return.
