The Argentinian apparently refused to come on as a substitute and has been suspended by the club for two weeks while they try to resolve the issue.
Wolves boss Mick McCarthy said: "The suspension is the right course of action. It's a difficult one for the people at Manchester City handling it because you are damned if you do and damned if you don't.
"Everyone has got an opinion on it. It is a very visible high-profile thing.
"What he did was completely wrong. I might have left him on the tarmac [in Germany] actually."
Tevez, 27, has refuted the claims by saying that there was a misunderstanding on the touchline but he has been widely criticised for his actions.
Ipswich boss Jewell told BBC Radio Suffolk: "I have to be careful because I don't know exactly what's gone on, but refusing to come on and play football, no matter how much you get paid, is beyond apprehension.
"If he has refused to come on, Manchester City have a great opportunity to make him sweat by not letting him go, and if one team in the world have the money to do that it's Man City.
"He's a great player - sorry - he was a great player, he's no longer a great player in my eyes after he's done that, it's outrageous."
It is not known whether Tevez will wear a City shirt again but Mancini is due to meet with the club's board on Thursday.
