Bedford sprinter Nigel Levine has been provisionally suspended after he failed a drugs test.
The 400m runner, who grew up in Northamptonshire, allegedly tested positive for the banned asthma drug clenbuterol.
Levine has the right to respond to the charge and will be offered a full UK Anti-Doping hearing.
The 28-year-old was hoping to return to the sport in the near future after he broke his pelvis in a motorbike crash in Tenerife back in January 2017.
"UK Athletics has today announced that athlete Nigel Levine has been provisionally suspended from participating in athletics after being charged with having committed an anti-doping rule violation contrary to IAAF Anti-Doping Rule Article 2.1 (Presence of a Prohibited Substance or its Metabolites or Markers in an Athlete’s Sample)," a UK Athletics statement read.
"The provisional suspension was issued by UK Anti-Doping and is in accordance with IAAF Anti-Doping Rules.
"The individual now has the opportunity to respond to the charge against him including the right to a full hearing of the case."
Clenbuterol is used to relieve breathing disorders such as asthma, but is on the World Anti-Doping Agency's prohibited list because it can sometimes lead to weight-loss.
