The school announced the suspension about 75 minutes before kickoff.
Gators head coach Jim McElwain did not address why Robinson was suspended when speaking to media postgame.
"It's just a personal choice a guy made," he said. "Are you any of you surprised? I mean, really? What's disappointing is that someone would do that to their teammates, and yet, I'm not mad at him at all. He just made a choice."
Saturday's game marked the fourth time Robinson has been suspended while with the Gators. He was suspended twice as a freshman and for the 2014 season opener against Idaho, a game that was canceled because of thunderstorms. Robinson has also been benched or demoted twice this season.
When asked when Robinson would return, McElwain said only, "It's up to his teammates. Who knows whether he can choose to do what's right or not? I don't know."
Tight end Jake McGee added: "That's something we'll keep in house and go from there."
Robinson, a native of Fort Valley, Georgia, leads the 12th-ranked Gators (10-1, 7-1 SEC) with 47 catches and is second on the team with 505 receiving yards. He has two touchdowns this season. For his career, Robinson has 105 catches for 1,338 yards and nine touchdowns.
