Brawn is one of very few people who have access to Schumacher and in an interview with BBC Sport, Brawn said that the German is showing encouraging signs.
"There are encouraging signs and we are all praying every day that we see more of them. So it is difficult for me to say very much and respect the family's privacy."
"All I would say is there is a lot of speculation about Michael's condition."
"Most of it's wrong and we just pray and hope every day that we continue to see some progress and that one day we can see Michael out and about and recovered form his terrible injuries."
