Motorcyclist Karel Abraham doubtful for Indianapolis Grand Prix following injury


Czech motorcyclist Karel Abraham is uncertain to start in Sunday’s Grand Prix even in Indianapolis, in the US. He took part in Friday’s training but only completed 12 courses of the circuit before his father called off the practice. He was complaining of slow reflexes and poor concentration. The rider suffered concussion following training for the Brno Grand Prix two weeks ago and has not fully recovered since.
