Redirect with . htaccess

Question

I am using the following mod-rewrite rule

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/([^/]+)/?$ index.php?lang=$1&page=$2 [L,QSA,NC]

But now I need to redirect an old page to the new one. So I did the following:

Redirect 301 /port/reestruturacao-financeira http://website.com/port/reestruturacao-corporativa/

Where the second is the new page. But the browser returned this:

http://website.com/port/restructuracao-corporate//? lang=port&page=financial restructuring
