It has now been two weeks and Miami Dolphins running back Jay Ajayi has still not been cleared to return to full-contact practice for the team due to the concussion he suffered prior to that time frame. This is now turning into quite a bit of a problem as fantasy football drafts are fully underway and expectations for Ajayi as a rare bellcow back in a run-dominant offense are sky-high. Right now Ajayi is being picked right near the top of Round 2 but if he doesn't return soon, that lofty draft status is not going to look so hot. Also the threat of additional concussions are always a major red flag as well and so Ajayi becomes another question mark in a position that has been marred with issues involving the big names at or near the top of this list. Ezekiel Elliott has already been suspended for six game and Le'Veon Bell is holding out and drawing concern about what kind of shape he may be in when he does return. Throw in the hamstring injury of DeMarco Murray and Ajayi's concussion and there are a slew of questions marks going around to muddle drafts. That just makes guys like David Johnson, LeSean McCoy, and Devonta Freeman that much more valuable.
