According to the Raptors, the altercation took place after Toronto's 124-107 loss to the Oklahoma City Thunder on Wednesday. The Raptors said Ibaka was suspended for a violation of team rules.
"We've discussed this internally as a team, and we won't be discussing it any further," Raptors president Masai Ujiri said in a statement. "Now we're focused on moving forward together, and we look forward to having Serge back in the lineup."
The suspension will cost Ibaka $139,000.
Raptors coach Dwane Casey would not share details of the incident but said Ibaka and the staffer had apologized to one another. Casey said the situation had been "resolved."
"It went over the limit, and we've handled it," Casey said.
The Raptors won 111-98 on Friday for their 11th straight home win.
