Injured Renault driver Robert Kubica could still make his return to Formula 1 in 2011, according to his manager Daniele Morelli.
Renault boss Gerard Lopez said Kubica, who was injured in a rally crash in February, would not race this season but may take part in a Friday practice.
But Morelli told BBC Sport in Monaco that was not necessarily the case.
"I wouldn't suggest betting Robert won't be back before the end of 2011," Morelli said.
"What Lopez said is not corresponding with the information that we have. There is no basis to make such a statement."
Kubica is recuperating at his home in Monte Carlo after suffering a partially severed hand, as well as arm and leg fractures in a high-speed rally crash in Italy's Ronde di Andorra.
Nick Heidfeld is standing in for Kubica at Renault but Morelli says it is still too early to rule the Pole out of returning to his race seat with seven months of the season left.
He also questioned Lopez's suggestion that Kubica would return first in what is considered to be a more junior Friday testing role.
"We [speak] daily with Robert, we know what the doctors are saying, what [Renault team doctor] Dr Ceccarelli, who is coordinating the recovery programme, is saying," Morelli continued.
"We have a lot of information and what Lopez is saying is not corresponding with the information that we have.
"To give a Friday session to Robert is the minimum that the team should give to support its driver. It looks to me kind of an insufficient proposal.
"When Robert is back, he will be back because he will be capable of doing what he did the day before the accident."
Kubica had a small operation earlier this month to remove adhesions that were affecting the functionality of his right forearm and elbow muscles.
The 26-year-old, who spent 10 weeks recovering in the Santa Corona Hospital in Italy, is now expected to begin a normal training programme by the end of July.
