London - Olympic champion Mo Farah admits he faces a race against time to be fit for this month's Commonwealth Games.
Farah, who won gold in the 5 000m and 10 000m events at the London 2012 Olympics, pulled out of last weekend's Glasgow Grand Prix after suffering from abdominal pains.
The 31-year-old will now make a decision on contesting the 5 000 metres and 10 000m at the Commonwealth Games back in Glasgow "further down the line".
"It's a good question, I don't know," Farah told the BBC when asked whether he would be ready for Glasgow.
"Hopefully I should be good, but I kind of missed a bit of training, and obviously I pulled out of the weekend's Grand Prix.
"So I'm actually just going to get back into full training, and then we'll see."
Farah, who won gold in the 5 000m and 10 000m at the 2013 World Championships, said team doctors have given him the "all-clear" to return to training, but admitted he remains unable to confirm his participation at the Glasgow event, with track and field competition starting on July 27.
"I came back and had some tests done through British Athletics, which went well and now I've got the all-clear to get back into training, and I'll see what I can do," he said.
"I'm just saying where I am right now.
"My aim is to compete in both events, but at the same time I'm getting back into training, I'm having this bit of training, but you know, we'll make a decision further down the line."
Farah is scheduled to race over two miles on the roads of central London at the Anniversary Games on Sunday, but that participation would now appear to be in doubt given his comments.
