Davidson got tagged for five runs on five hits and two walks while striking out two over 2.2 innings of relief in Monday's 11-2 loss to the Nationals.
The southpaw was thought to be in line for Tuesday's start, but instead Davidson got used to mop up at the end of a bad loss Monday. Bryce Elder is now getting called up to take the mound Tuesday, and for the time being, Davidson may have missed his chance to show he can hold down a consistent spot in the rotation. If Elder struggles in his big-league debut, however, Davidson might be right back in the mix.
