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

Players had Tuesday off following their game on Monday night in Cleveland, but they were back on the fields today at the Quest Diagnostics Training Center.

The Giants are preparing for the all-important third preseason game, which is regarded around the league as the dress rehearsal for the regular season. They will "host" the Jets on Saturday night in the annual MetLife Bowl.

Here is what we learned at Wednesday's practice:

•   Eighteen days away from Week 1 in Dallas, the Giants find themselves a little thin at wide receiver. That stems from injuries to Odell Beckham Jr. (ankle) and Brandon Marshall (shoulder), who both went down in the game against the Browns. The Giants also today waived/injured wide receivers Darius Powe and Andrew Turzilli, who have hamstring injuries. Coach Ben McAdoo said Beckham is getting treatment and they will take it "day by day" with him. The same goes for Marshall.

•   In their place, Roger Lewis and undrafted rookie Travis Rudolph saw time running with the ones on Wednesday. Lewis, who made the team as an undrafted free agent last year and caught two touchdowns as a rookie, had a productive day with some big receptions from Eli Manning at practice.

"I think Roger had a great day at practice, showed up ready to go, worked hard, got a lot of reps on special teams and on offense," McAdoo said. "He made some nice catches down the field on some post balls and some go balls and on some flies, had a very productive day. He took advantage of his opportunity."

•   The facility is still buzzing about Olivier Vernon breaking up a pass 30 yards downfield against the Browns, which is pretty remarkable for it being two days after a preseason game. Then again, the play was remarkable.

"It's going to be a long game for me if I have to do that all the time," the 6-foot-2, 262-pound defensive end said. "I mean, basically we just had to drop on the tight end and just had to stick on him until I found some help and unfortunately, it didn't come, so I just had to stay on him."

"That was pretty impressive," middle linebacker B.J. Goodson said. "That was really, really impressive. I was one of the first guys to go in and congratulate him on that play. That was a very impressive play by a defensive end. So I was excited about it."

•   Speaking of plays in the secondary by non-defensive backs, linebacker Jonathan Casillas had an interception today off quarterback Josh Johnson. But the attention on the linebacking group this summer has gone to Goodson, a second-year pro who has taken over as the starting middle linebacker after only playing 13 defensive snaps as a rookie. He had a team-high seven tackles against the Browns, including a sack for the second consecutive game.

"I'm running the show," Goodson said. "So, at the end of the day, what I say goes. The guys trust me, [defensive coordinator Steve Spagnuolo] trusts me, and that's what matters."

•   Brett Jones, who has mostly been backing up Weston Richburg at center, took some snaps with the first team at right guard, a position held by John Jerry. "Brett does some good things for us," McAdoo said, pointing to the fact that the Giants played a game 36 hours before today's practice. "He's a tremendous communicator, whether he's at center or guard."

•   In addition to waiving the two injured receivers, the Giants also released offensive linemen Michael Bowie and Corin Brooks. Taking their places are offensive linemen Richard Levy and Matt Rotheram and wide receivers Marquis Bundy and C.J. Germany.

•   The Giants practice again tomorrow in advance of Saturday night's game against the Jets. They then turn around to face New England on the road in the preseason finale next Thursday. The 53-man roster will be set on Saturday of Labor Day Weekend.
