Zimbabwe opening batsman Mark Vermeulen has been thrown off the team's England tour for persistent misconduct.
Vermeulen had already been warned
A disciplinary hearing held at the team hotel in Durham on Sunday morning decided the 24-year-old should be sent home immediately.
Zimbabwe team manager Babu Meman said: "Mark has been warned about his conduct on a number of separate occasions during the tour but unfortunately has not heeded that advice.
"The final straw concerned an incident that took place at the end of play on the Friday of the Test.
"Mark ignored a management instruction to travel with the rest of the squad on the coach, which is a practice followed at all games to promote team morale and adhere to the security advice we have been given for the tour.
"Instead he left the ground on his own, deliberately ignoring a perfectly reasonable request."
Vermeulen - who made a pair at Chester-le-Street - played in both of the Tests against England and would have remained in the squad for the one-day series.
Zimbabwe coach Geoff Marsh said: "Mark is a talented player but he has to learn that the team comes before personal considerations.
"His poor behaviour means that he will now miss the opportunity to continue learning about international cricket.
"That is very disappointing for him personally, but even more so from the team perspective."
Further disciplinary action will be considered by the Zimbabwe Cricket Union Board when Vermeulen returns home later this week.
Later on Monday, Zimbabwe decided not to fly an additional batsman out to cover for Vermeulen in the one-day tournament which also features South Africa.
The five one-day specialists, Gary Brent, Charles Coventry, Stuart Matsikenyeri, Waddington Mwayenga and Richard Sims are all flying in.
Vermeulen, Mluleki Nkala, Barney Rogers and Vusi Sibanda make way for them as the size of the squad is increased marginally from 15 to 16.
Zimbabwe one-day squad: Heath Streak (captain), Tatenda Taibu, (v/captain and wicket-keeper), Dion Ebrahim, Grant Flower, Sean Ervine, Stuart Carlisle, Travis Friend, Andy Blignaut, Doug Hondo, Ray Price, Douglas Marillier, Gary Brent, Waddington Mwayenga, Stuart Matsikenyeri, Charles Coventry, Richard Sims.
