Ajayi (hamstring) is listed fourth on the Dolphins' initial depth chart, the Palm Beach Post reports.
Analysis:
Damien Williams is listed second, with LaMichael James holding down the third spot. Ajayi still has a shot to beat out both players for the top backup job, but his work in pass protection has reportedly been shaky and the hamstring injury will likely keep him out of Miami's first preseason game.
