Beckham was "very sore" on Tuesday morning, a source told ESPN.
The injury occurred when Browns cornerback Briean Boddy-Calhoun hit Beckham just above his right knee on a high pass thrown by Giants quarterback Eli Manning. As for Marshall, McAdoo revealed that X-rays were negative on the veteran receiver's shoulder, per Jordan Raanan of ESPN. He underwent an MRI on Tuesday that confirmed a sprained ankle.
Beckham took a low hit from a Browns defender which forced him to leave the game.
Coach Ben McAdoo said the team would see how Beckham responds to treatment.
Beckham didn't appreciate the hit and limited his postgame remark to say: "I don't know".More news: Police seize stash of Trump-shaped ecstasy tablets

"I don't know man, I'm pretty concerned, but I think I'll be alright", he said. The game-sealing play was similar to the one Boddy-Calhoun delivered in the preseason opener, when he made a tackle for loss on fourth-and-goal.
Beckham's college teammate and good friend, Jarvis Landry, took to Twitter after Beckham's injury to express his displeasure with the National Football League preseason. Saying he's only to miss a game or two would undersell the severity and allow the Giants to force opponents to game plan for him.
Charles Robinson of Yahoo Sports reports that Beckham is exploring the possibility of taking out an insurance policy worth roughly $100 million if he has to play out the 2017 season on his rookie deal. McAdoo did decline to state if Beckham had a high or low ankle sprain, simply stating "It's an ankle". I'd like to see him complete the shallow cross to (wide receiver) Sterling Shepard in the red zone.
"We were just praying over the country and praying over things going on", Kirksey said.
The New York Giants starters still haven't scored a touchdown yet in the preseason.
