Dai Greene has revealed he has doubts over his medal aspirations for this year's Commonwealth Games, despite being the defending champion over the 400m hurdles.
The Welsh athlete, 28, won gold in Delhi four years ago with a time 48.52 seconds, but has not competed since, having three hernia operations last year.
In fact, the world champion in the event from 2011 has been dogged with injuries ever since he agonisingly missed out on a medal at London 2012, finishing fourth.
The latest setback, however, is one which has Greene with doubts as to how well he can perform in Glasgow, reports BBC Sport.
"It depends on how well everyone else is running as to what I can realistically achieve," he said. "I'm not going to be in the best shape I've ever been in.
"I won't know until I'm fully going over the hurdles again, which will happen in the next few weeks. There are still five weeks to go and a lot can change in that time."
He has been named in the Welsh squad for the Games despite revealing he will miss the British trials this weekend.
He is, however, aiming to achieve the qualification time for the European Championships in August. The deadline for the entry standard is mid-July, but is something Greene is hopeful of achieving.
"I know when the closing date is, which is halfway through July. So I'll be racing before then. After that is the Commonwealths and fingers crossed I'll be in better shape than I am now."
