Midway through the workout at the Quest Diagnostics Training Center, the players headed en masse to the field house to drink water or Gatorade and to cool off. At the conclusion of the five-minute hydration period the players returned to the outdoor field and resumed practice.

Several players had to leave the opening practice yesterday with heat-related issues. A breeze and cloud cover made it cooler today, but Coughlin kept the break on the schedule.

"I said I was going to do it, so I went ahead and did it," Coughlin said.

A practice halftime could become a permanent part of the schedule.

"If I keep it, it will be because of the heat we experienced yesterday and there's nothing wrong with that," Coughlin said. "It does give them a sense of second half, first half. Gives them a sense of having an opportunity to cool a little bit and come back and go."

• Wide receiver Odell Beckham Jr., the team's first-round draft choice this year, did not practice because of a sore hamstring, the same issue he had in the spring. Coughlin said Beckham aggravated the soreness after tripping while running a pass route yesterday.

• A former first-round selection, David Wilson, is happy to be back on the field after receiving medical clearance to return to the field on Monday. Wilson missed the last 11 games of the 2013 season with a neck injury.

"He's a highly-conditioned athlete," Coughlin said. "He can run and run and run.  I don't think today was quite as effective as yesterday, but he was out there fighting away."

Coughlin was asked if Wilson had any limitations.

"He's been cleared to play," Coughlin said. "If there are any limitations, it would be something I would impose. Like I told you yesterday, he is an amazing guy.

• Linebacker Jameel McClain participated in the entire practice after leaving early yesterday with a foot/shoe issue.

"He did well," Coughlin said. "He came out and practiced and went the whole practice, so I think he's fine. A little sore, but he was able to go."

• Brandon Mosley, who left practice early yesterday with an upset stomach, was back as the first-team right guard. John Jerry also took some snaps there with the starters…Wide receiver Mario Manningham, who missed the spring work while rehabilitating his knee, made a nice catch today.
