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

With three days to go until the preseason opener, the New York Giants were back on the field Tuesday for training camp practice No. 10. It was a bounce-back day for the offense, so let's get to it.

Here's a recap of the day:

•   Yesterday, the defense went 3-for-3 in keeping the offense out of the end zone in the two-minute drill. That wasn't the case on Tuesday. In today's scenario, the offense needed a touchdown and a two-point conversion. Quarterback Eli Manning led the first team and hit wide receiver Odell Beckham Jr. for a first down, setting up a touchdown to rookie tight end Evan Engram down the seam, just like the Giants envisioned when they drafted him in the first round this past April. However, the job wasn't done; they still needed the conversion. That's when veteran wide receiver Brandon Marshall put a nice double-move on cornerback Janoris Jenkins in the end zone for an open throw-and-catch.

"It was a drill that was simulated after our two-score plan, so we're down by 10, you kick the field goal first, you come out, you go down for the touchdown, possible two-point conversion to either win or tie the ball game, depending on the score," coach Ben McAdoo said. "The first group made a nice play, had a chance to get the ball in the end zone there and go for it. Brandon ran a nice double-move there for the two-point play, so that was good to see."

•   The offense won the first round of the drill, but the defense won against the second (Geno Smith) and third (Josh Johnson) units. Wide receiver Dwayne Harris almost won it for the second group, but the ball was ripped away at the last second in the end zone. The referee at practice called it a touchdown, but coach Ben McAdoo ran in to call it incomplete, so that's what they went with on the field -- his practice, his rules. In a game, that might not be the case. Next up were the threes, and the defense recorded a walk-off "sack" to win the drill (no contact is allowed with the quarterbacks in red jerseys).

"The defense had some nice drills as well – the seven-on-seven, all third down, the tight red and green (zones)," McAdoo said. "It's a tough drill for the offense, and the defense had a nice drill there."

•   Outside of the two-minute drama that had everyone craving real game action, tight end Matt LaCosse had the play of the day, making a tough catch down the sideline while falling backwards with defenders draped over him.

•   The Giants went heavy with the green/red zone work today. Manning, after a series of checks, got the offense in the right play and hooked up with a wide receiver Roger Lewis for a nice touchdown from inside the 10. Manning had another touchdown to Beckham later on from near the goal line. Shortly after that, Smith found wide receiver Darius Powe for another score.

•   Colin Thompson, an undrafted rookie tight end from Temple, flashed a few times and caught a touchdown from Johnson during seven-on-seven work. Rookie quarterback Davis Webb also had a great pass to him during the "opportunity" period, which is intended to give young guys a chance to show what they've got.

•   Rookie defensive tackle Dalvin Tomlinson, the Giants' second-round pick, flashed at times in the fully padded practice. "I'll get in there and take a look at the tape here, but he did flash," McAdoo said. "He's working on his transition rush, and it's certainly showing up on the field."

•   Safety Trey Robinson made a nice play to break up a pass from Johnson to wide receiver Keeon Johnson. Cornerback Janoris Jenkins also looked like he had an interception in the end zone but was ruled out of bounds. He didn't exactly agree with the call when asked about it after practice.

•   McAdoo had some injury updates after practice. Defensive tackle Robert Thomas (soreness), linebacker Mark Herzlich (stinger) and defensive back Mykkele Thompson (quad) did not practice. Rookie defensive end Avery Moss left early with a shoulder issue.

•   The Giants practice again tomorrow, the last one open to the public before Friday night's preseason opener against the Steelers.
