Boss suffered his second concussion in less than a year last Sunday when he was hit in the back of the helmet on an overthrown pass during the Giants' 31-18 win over the Carolina Panthers.
"I think they are just trying to be conservative about it," Boss said. "They don't want to have one of those things where I get concussed in back-to-back weeks and then I am stuck missing a big chunk of time."
"I'm pretty certain I will be back the following week."
Boss suffered a concussion last Thanksgiving against Denver and the tight end understands why the team wants to play it safe.
Boss said he has not experienced any severe headaches. He expects to undergo more tests this week.
"Honestly I've felt pretty good," Boss said. "It was one of those [situations] where I usually get hit and I pop up and it takes me a few moments to kind of gather myself and get up. With this one, it dazed me a little bit more and I was slower to get up and wasn't able to get up off the ground quick enough before the trainers got out there so they put a halt to me getting up and walking off."
The Giants signed tight end Bear Pascoe off the practice squad this week since they had one healthy tight end in Travis Beckum. Coach Tom Coughlin was forced to play tackle William Beatty at tight end against Carolina and Beatty broke a bone in his foot that will sideline him indefinitely. Beatty will undergo surgery on Thursday.
Umenyiora is dealing with some "wear and tear" on his surgically repaired left knee and Nicks is recovering from an ankle injury he suffered during the win over the Panthers. Nicks said he rolled his ankle during the second quarter but continued to play on it. He scored three touchdowns against the Panthers.
"It's just a little sore today," Nicks said. "It will be fine."
Coughlin said both Umenyiora and Nicks are expected to practice on Thursday.
Cornerback Aaron Ross was scheduled to go through a full practice on Wednesday for the first time since injuring his plantar fascia late in the preseason.
