The 24-year old is still yet to obtain the work permit required to officially join the English Championship club but Warzycha has indicated the Crew will be without his services in 2012.
However, if a visa is not sorted, Warzycha says that the club will be able to accommodate Rogers.
"We have to think about life without Robbie, but if he doesn't sign [with Leeds] and he comes back, we can make it work," Warzycha told MLSsoccer.com.
But Warzycha is confident that the USA international will land at Elland Road as the club has spent the wage money allocated to both Rogers and Emmanuel Ekpo who departed at the end of the 2011 season.
"With so many offers out there, we've spent that money that would have been earmarked for [Ekpo and Rogers]," he added.
