According to the Chicago Tribune's Brad Biggs, Bears' guard Kyle Long did not travel with the team to New York: 

While the reason for Long's absence is unclear, the veteran did get in two separate fights during practices on Sunday afternoon and Wednesday night. After Tuesday night's scrap, head coach Matt Nagy mentioned that while punishment would be handled internally, he expected more maturity out of his players. 

“You know, [Sunday] to me was a little bit more of a pillow fight,” he said. “[Wednesday] I thought was a little bit, just like I said, it's disappointing… 

... Again, it’s all that kind of stuff where we’re more mature than that. I know that I personally expect more from us.”

Had he traveled with the team, it's unlikely that Long would have played much, if at all. He did not appear in the Bears' preseason opener against Carolina.
