EAST RUTHERFORD, N.J. -- A daily review of the hot topics coming out of training camp:

Giants coach Tom Coughlin was not at all happy that four of his players had to leave the team's first practice of training camp with heat-related problems. Guard Brandon Mosley, who had been working at starting right guard in place of the retired Chris Snee, was carted off early in practice. The cart also came for linebacker Spencer Adkins and tackle Charles Brown for what Coughlin described as heat-related issues, and Coughlin made it clear in an interview with Sports Illustrated's Don Banks that he was not pleased about it. The Giants will look to make it all the way through their second practice Wednesday, when the high temperature is forecast to be 92 degrees. The high Tuesday was 89.

Linebacker Jameel McClain was also carted off, but that was due to a foot injury. X-rays on McClain's foot were negative, which is good news for the Giants as McClain is filling in for middle linebacker Jon Beason, who also has a foot injury but hopes to be back in time for Week 1. For what it's worth, rookie Devon Kennard continues to look good at linebacker. He worked on the strong side but has been mentioned as someone who could handle the middle linebacker responsibilities.

Rookie wide receiver Odell Beckham, Jr., the team's first-round pick, pulled up short on a pass route in practice, leading to an interception of Eli Manning by Dominique Rodgers-Cromartie. Coughlin seemed annoyed about that and said of Beckham, "He has a ways to go." Earlier in the day, Beckham told us he was planning to watch out for and be careful with the hamstring injury that held him back in minicamp. It's possible the incident here was an example of that, but Beckham's health and overall progress will be worth watching as camp goes along. He has obvious blazing speed and good hands, but he will need to run his routes and run them again if he's to advance to the point where he's a Week 1 helper in the new offense.

Manning shows absolutely no ill effects of the ankle surgery that sidelined him for a portion of his spring work. He's practicing as usual and seems excited about working in the new offense.

The Giants used rookie running back Andre Williams as the goal-line back during that portion of practice Tuesday. Williams likely could slide into that role right away while he works on the finer points of his NFL game as a rookie.
