Giants.com brings you Training Camp notes and observations straight from the sidelines:

The Giants are in the dog days of camp now.

Heading into an 11-day span that includes three more preseason games, the team held practice No. 14 on Tuesday at the Quest Diagnostics Training Center. They officially break camp today, but the work is only beginning.

"This week is going to be our most challenging week," coach Ben McAdoo said. "We have three games in 11 days coming up. So we need to make sure we get the most out of this week right here and that's by design. We're going to be a little heavy-legged and we're going to be sore, but we're going to build calluses. When we get our legs back, it's going to lead to great things for us, but we're not going to get them back any time soon."

Here is a recap of the day:

•   The Giants worked extensively near the goal line, both with the offense's back against it as well as the defense's. That's where wide receiver Brandon Marshall tried to one-up Odell Beckham Jr.'s catch from yesterday and caught his own one-handed touchdown from Eli Manning in the corner of the end zone. The ref called him out of bounds, but the tape showed he got both feet in. "That was pretty special, that was good," Marshall said. "But, again, like I told [Odell] today when we were running gassers, he's not going to keep it easy. I'm going to push him every chance I get. I want my little moment, too, so I try to make me a little Odell one-hand catch, but it will probably make the top 20, not the top five."

•   Rookie tight end Evan Engram also showed his tightrope ability shortly after that, getting both feet in bounds in the middle of the back of the end zone. That one was also from Manning.

•   Undrafted rookie wide receiver Jerome Lane broke through with a big day, beginning with a touchdown from Josh Johnson. He was only getting started. Lane later hauled in a deep pass down the left sideline from Geno Smith and scattered a handful of other passes throughout the afternoon, including another touchdown from Johnson.

•   Pro Bowl cornerback Janoris Jenkins got one back for the defense and made a great play to break up a pass intended for Marshall in the end zone. Jenkins was on the wrong end of Beckham's one-hand, windmill catch from yesterday. The fact that he's one of the best corners in the game only upped the level of difficulty.

•   Middle linebacker B.J. Goodson was unable to finish practice because of a sore back that happened as a result of jamming a receiver. Fellow linebacker Devon Kennard was also sore, leading to more reps for Curtis Grant and Calvin Munson. All-Pro safety Landon Collins missed practice with an illness. Andrew Adams took snaps in his place.

•   Smith, the No. 2 QB today, and rookie running back Wayne Gallman were sent to run a punishment lap after a few bad exchanges. "The ball was on the ground way too much today," McAdoo said. "We needed an opportunity to gain our composure, so I gave a couple players an opportunity to gain their composure."

•   Linebacker J.T. Thomas, who has been working back from a torn ACL suffered in the 2016 season opener, and running back Shaun Draughn, who was dealing with an ankle injury all summer, were activated off the physically unable to perform list today after passing their physicals. McAdoo said they will build Thomas up but there is a good chance he will not play in the upcoming preseason game in Cleveland.

•   The Giants today signed former Boston College linebacker Steven Daniels as well as former Saints defensive lineman Bobby Richardson. Defensive tackle Corbin Bryant injured his elbow yesterday and was placed on injured reserve

•   Veterans can check out of the team hotel now as players enjoy a day off tomorrow. When they come back from the break, the team will jump into a mock game week to prepare for their trip to play the Browns on Monday night.
