Dolphins' Jay Ajayi: Returns to practice

Ajayi (knee) returned to practice Friday, the Palm Beach Post reports.

Analysis:

Ajayi was held out of practice all week before Friday's full-padded session due to a bone bruise in his left knee. Although he was able to return to end the week, coach Adam Gase said he knows Ajayi isn't 100 percent healthy yet. While the second-year back was sidelined, veteran signing Arian Foster distinguished himself to many as the Dolphins' best running back, so by taking the practice field once again, Ajayi can at least avoid losing further ground to Foster as they prepare for the upcoming campaign.
