Patriots training camp kicked up a notch on Monday, as the team put pads on for the first time this summer. One player returned from an injury, while another left the field.

How will the Patriots' offense fare against the defense when the pads come on? The first step to finding answers begins on Day 5 of training camp practice. After missing the first four practices, second-year wide receiver Ja'Lynn Polk is on the practice field and in pads.

The first padded practice of this training camp was an unexpectedly eventful one, as cornerback Christian Gonzalez left the field early after suffering an apparent lower body injury. With Carlton Davis already out, the Patriots’ cornerback depth took an early hit.
