Segura left Saturday's game in the top of the ninth inning due to an apparent finger injury, Greg Johns of MLB.com reports.
Johns said Segura appeared "to dislocate a finger on [a] play at second," but it's best to wait on specifics of the injury until the team announces it. The Mariners' waning playoff chances would be dealt a significant blow if Segura has to miss time with a little more than one week in the regular season remaining. Taylor Motter replaced Segura at shortstop upon his departure.
