Champions Red Bull and rivals Ferrari have been forced to change their plans for the final pre-season Formula One test after the sport\'s governing body ruled that all testing must end by Sunday. Both teams had planned to start the test at Barcelona\'s Circuit de Catalunya on Friday, a day later than others, and run through until Monday. However, they changed their plans after the FIA clarified that no testing can take place in the week preceding the first event of the championship in Melbourne.
