Taylor required an MRI on his thumb Sunday morning, but the results of the tests aren't yet available, MLB.com's William Ladson reports.

EDGE Analysis

The Nationals were apparently concerned that Taylor sustained some ligament damage during his 2-for-3 performance Saturday against the Marlins, so he was held out of Sunday's regular season finale while the team investigated the issue. If Taylor's injury is deemed even mildly serious, that might be enough to prevent him from cracking the Nats' NLDS roster.
