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.

Fourth-round rookie Joshua Farmer and former practice-squad signing Jaquelin Roy were first off the bench with Tonga. Farmer and Roy struggled in 1-on-1 pass rush, where the rookie got tossed to the ground and Roy lost both reps.
