 The colours of his 2001 World Championship medals would change in 2005 as both his placings were improved – he received bronze in the 100 m and the bronze relay medals were upgraded to silver after all the times and performances of the American sprinter Tim Montgomery (who was second in the 100 m and won the 4 x 100 m with the US team) were nullified due to serious doping violations.That brought Boldon's career total to four World Championship medals, to match his four Olympic medals.Boldon was seriously injured in a head-on crash with a drunk driver in Barataria, Trinidad and Tobago, in July 2002, and never again ran sub-ten seconds in the 100 m or sub-twenty seconds for 200 m, something he had done on 37 separate occasions prior to 2002.
