Heat returns to practice; Dobson rises

FOXBOROUGH, Mass. -- Traditional late July heat returned for the second day of Patriots training camp, as the team embarked on its second on-field workout on the practice fields outside of Gillette Stadium on Saturday morning.

The team once again worked in helmets and T-shirts, as the NFL's collective bargaining agreement prohibits full-pads practices until the third day of on-field work. Head coach Bill Belichick reiterated in pre-practice remarks that the team will work in full pads on Sunday.

Defensive linemen Armond Armstead (non-football injury list) and Corey Grissom (unknown) were the only players not spotted at practice.

Tight end Rob Gronkowski (back/forearm), wide receivers Julian Edelman (foot) and Mark Harrison (foot) and offensive lineman Nick McDonald (unknown) were on the field but not dressed to participate in practice.

Defensive back Devin McCourty (offseason shoulder surgery) was the lone non-quarterback to wear a red (no-contact) jersey.

A crowd that appeared to exceed the opening day of camp's roughly 6,900 total packed the stands, offering enthusiasm throughout the two-plus-hour workout.

The warm weather aided the passing game, which got back on track after a slow start on Friday. Rookie receiver Aaron Dobson and Kamar Aiken both had good days, making impressive catches down the field. Defensively, cornerback Alfonzo Dennard made multiple pass break-ups.

Also, rookie free agent Kenbrell Thompkins increased his workload and showed up at times.
