Kelley has been unavailable the last few games due to a finger laceration, Jane Lee of MLB.com reports.

EDGE Analysis

Kelley hasn't pitched since Aug. 29, but it's not clear when exactly he sustained the laceration. The veteran right-hander has allowed only two hits and a walk over 8.2 scoreless innings since joining the A's at the start of August. It doesn't appear to be a long-term issue, but Kelley may not be available until after Thursday's scheduled off day.
