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

As the Giants wrap up their stretch of three games in 11 days, the team on Monday returned to the practice fields at the Quest Diagnostics Training Center. This is always a unique week for players, coaches, and front office staff as they balance the final preseason game, the 53-man roster and, of course, the season opener, which is less than two weeks away in Dallas.

"There really is no week in the NFL like this fourth preseason game/beginning of opening week," linebacker Jonathan Casillas said. "There's nothing really like that at all, besides this time of year. The worst day in the NFL is coming up soon, which is the cut day."

Here is what we you need to know about Monday's practice:

• The Giants got back one of their star wide receivers, albeit in a limited role. Brandon Marshall, who suffered a shoulder injury against the Browns and missed the third preseason game, returned to practice today and took some team reps. "He looked good," coach Ben McAdoo said. "He caught a nice ball on a slant route, was moving around, got a little bit of work today. So it was nice to have him back in the mix."

• Meanwhile, Odell Beckham Jr. remains sidelined with an ankle injury, which he also suffered in Cleveland. "He's getting treatment," McAdoo said today, and has said every day since the injury. "He responded well to treatment, and we'll repeat that process again for tomorrow, so you don't have to ask the question."

• Defensive tackle Jay Bromley is still sore after spraining his left knee against the Jets. The Giants are taking it day by day with him right now. Bromley said tests revealed "no significant damage."

• McAdoo gave a firm "yes" when asked if second-round pick Dalvin Tomlinson is ready to start Week 1 in Dallas, pointing to the rookie's college experience at a juggernaut program like Alabama. "He's come in, he's learned the system very well, he's good with his hands, he plays with leverage, he destroys blocks," McAdoo said. "We feel he'll be ready to play Week 1."

• Defensive end Romeo Okwara, who took over last season when Jason Pierre-Paul went down in Week 13, is giving the defense some position flexibility right now as he spends some time at linebacker. The Giants are a little nicked up at the position and have some depth at defensive end. "We feel Romeo can handle it physically and mentally," McAdoo said. "And he's done a nice job for us in that transition."

• Speaking of linebackers, B.J. Goodson continues to show he can be a three-down linebacker and made a nice play in coverage today as he broke up a Geno Smith pass intended for tight end Rhett Ellison down the middle. Cornerback Dominique Rodgers-Cromartie and defensive end Jordan Williams had interceptions today. The latter was initially deflected by cornerback Donte Deayon, who had a 36-yard interception return for a touchdown against the Jets.

• The Giants mixed and matched their first-team offensive line on Saturday, including Brett Jones and D.J. Fluker taking turns at right guard in place of John Jerry, but they returned to the normal combination today at practice.
• The Giants are sticking to a similar script from last year's preseason, McAdoo's first as head coach, meaning there's a good chance Eli Manning will not play in the final preseason game on Thursday night in New England.

• All-Pro defensive tackle Damon Harrison, who is entering his sixth NFL season and second with the Giants, had a rest day and did not practice.

• Yesterday, the Giants were awarded cornerback Tay Glover-Wright off waivers from the Philadelphia Eagles. There was an opening after they waived/injured rookie defensive end Evan Schwan, who suffered a fractured foot late in Saturday's preseason game against the Jets. Today, they placed offensive lineman Adam Gettis (foot) on injured reserve and signed cornerback Daniel Gray, who was released by the Arizona Cardinals last week.

• The Giants have until 4 p.m. on Saturday to reduce their active roster from 90 to 53 players.
