Robinson was ejected late in the second quarter of Sunday's 43-13 loss for kicking Vaccaro in the head at the end of a play.
"We do not tolerate that," coach Freddie Kitchens said after the game on Robinson's ejection. "That is unacceptable."
"I hurt the team, honestly. And I feel like if I could have it back, I would do things differently," the veteran left tackle told reporters on Monday. "It looked worse than it was."
Two players who were also ejected on Sunday -- Jaguars linebacker Myles Jack and 49ers linebacker Kwon Alexander -- are expected to be reviewed through the standard discipline process, NFL Network Insider Ian Rapoport reported, per sources informed. That almost certainly means no expedited process and no suspension, Rapoport added.
