Chelsea skipper John Terry must prove his fitness today to coach Fabio Capello.

The Guardian says Terry's chances of returning to the England line-up for Wednesday's World Cup qualifier in Belarus hinge upon the captain being fit enough for a full training session today as he continues his rehabilitation from a back injury.

Terry spent yesterday working on exercise bikes, in the swimming pool and jogging with the England physio, Gary Lewin, in a bid to prove his fitness ahead of the trip to Minsk while the rest of the squad took part in a warm-down session.

Fabio Capello remains hopeful the 27-year-old will be able to travel tomorrow for what is expected to be a more awkward tie. Terry will not make the trip unless he is deemed fit to play and it would be understandable for Chelsea to want him back at their Cobham training base for treatment, in the hope of having him available for the weekend trip to Middlesbrough, if the back injury persists.
