Burrows (PSU) report on \nbehalf of the\nSwift XRT team:\n\nOn 10 April 2004 we reported detection of a possible jet break in Swift XRT \ndata on GRB 050408, with additional observations scheduled to verify the \nbreak in the light curve (Godet et al. 2005, GCN 3222).  We now have \nanalyzed new data extending to about 300,000 s after the burst, and can \nstate that the reported possible jet break is not confirmed by the later \nobservations.  No jet break is seen in the XRT data up to 300,000 s after \nthe burst.\n\nAdditional observations are planned over the next several days to continue \nto search for a jet break in this afterglow.",
