Former captain Heath Streak has signed a contract to play for Zimbabwe after ending his 10-month dispute with the country's cricketing authorities.
Streak could soon be back in the Zimbabwe Test team
Streak, 30, was sacked last April after criticising Zimbabwe Cricket's selection policies.
"I just need to finalise some aspects of my contract with Warwickshire so that it ties in with my international commitments," he said in a statement.
"Otherwise I am ready to play for Zimbabwe when selected."
Streak added: "I am putting my weight fully behind captain Tatenda Taibu and the rest of the lads."
ZC managing director Ozias Bvute expects Streak to join up with the Zimbabwe squad currently in South Africa to play two Tests and three one-day internationals.
"Heath is immediately available for selection," Bvute said during the first one-dayer in Johannesburg.
"I look forward to seeing Heath here in South Africa, if the selectors deem him to be fit. He has been in good nick, getting runs and wickets, and I am confident he will play a part in this tour."
Following Streak's sacking, 14 players resigned in protest but Gavin Ewing, Barney Rogers and Andy Blignaut have also returned to the fold.
A Zimbabwe government committee is trying to resolve the overall dispute in meetings with the rebel players and ZC.
Batsman Stuart Carlisle said on Friday: "We had another good meeting and there is a strong possibility that more of us may return in the next few days."
"We want to come back because the International Cricket Council is talking about things like Zimbabwe playing home Tests only.
"We don't want it to get to that stage because that was never our intention."
Of the remaining rebels, Grant Flower (Essex) and Ray Price (Worcestershire) are unlikely to sign deals after committing to English county cricket next season.
Warwickshire, meanwhile, expect Streak to play for them this summer as planned.
Spokesman Keith Cook said: "We had an e-mail from Heath overnight via his agent in which he states that he wants to co-ordinate his international commitments with Warwickshire and incorporate our views into his thinking."
Zimbabwe's tour to South Africa ends in mid-March and they are not in action again until September, when they play host to New Zealand.
But Streak's situation will be discussed by the Warwickshire committee at a meeting on Monday.
