Our Argentine defender picked up the mysterious yellow card from referee Steve Bennett after a touchline bust-up involving Rovers boss Graeme Souness.
Mauricio certainly seemed the innocent party in the first half incident.
Souness was incensed when Mr Bennett refused to punish Chris Perry after the defender flattened Matt Jansen.
A throw-in was awarded instead which Mauricio went to take, a furious Souness exchanged words with him, Gus Poyet and Steffen Freund got involved and the result — a yellow card for the full-back.
Boss Glenn was clearly upset by the incident in his post-match press conference.
He said: “There will definitely be an appeal against that. The referee has definitely booked the wrong man because Tano has done nothing wrong. There is no way the lad should have been booked.
“Everyone saw what happened and I don’t want to see that in football. I’ll take it up with the right people. You better ask their manager, not me, what he did.”
One press man suggested Mauricio has been booked for ‘getting involved’ with Souness.
“He didn’t get involved with Souness,” Glenn responded. “Ask their manager. If he’s an honest man he’ll tell you what happened.”
Souness said he lost his cool after the initial challenge. “I just thought it was a really bad challenge," he said.
“Maybe I was too close to the action not to react. It's hard to be cool and collected all the time.
“Maybe the referee took his eye off the ball and ended up booking the wrong person.
“We have been punished wrongly in the past, but that's part and parcel of football. Referees have a hard job and can't see everything.”
Glenn Hoddle will appeal against Mauricio Taricco’s booking in Saturday’s defeat against Blackburn Rovers.
