Dolphins' Jay Ajayi: Knee issue

Ajayi missed Monday's practice due to a knee injury, NFL.com reports.

Analysis:

Ajayi was present at the Dolphins' practice to start this week, but was restricted to riding a stationary bike on the side. Afterward, the second-year pro downplayed the situation, saying he should only be out the next couple days due to a bone bruise in his left knee, the Miami Herald reports. With Ajayi out Monday, recently-activated veteran Arian Foster was able to lead the Dolphins' running back unit through practice.
