The former Orlando Pirates and Bidvest Wits forward rejoined the Urban Warriors last week after spending 2016 in India's Super League, with the team currently preparing for Tuesday's trip to joint-PSL leaders Bidvest Wits.
And Doutie, along with fellow January signings Rheece Evans, Rodrick Kabwe and Aubrey Funga, are all said to be coming along nicely as Ajax step up their mid-season preparations.
"On the physical and conditioning side I think Rodrick and Aubrey weren’t used to the intensity of our training so we had to take it a bit easier for the first two weeks or so. Fitness-wise they are there,” Greyling told the club’s official website.
"Sameehg on the other hand, he is flying and he is really fit because he only had a small break following the Indian Super League (ISL), before coming to us. He is really looking very good and he is 100 per cent fit."
Greyling went on to reveal that Ajax's only real fitness concerns are Toriq Losper, who is still a few weeks away from starting to run, and Ziyaad Eksteen, who strained ankle ligaments in training.
"There is not much news from the injury side of things, we are lucky to be blessed with an almost clean bill of health. The only player still recovering from a long-term injury is Toriq Losper; he is coming along very nicely and should be starting to do some linear running in the next two weeks which is a great sign.
"He is off his crutches, out of his brace so things are getting along well. In two weeks' time, he will start running.
"The only other injury we have is Ziyaad Eksteen, he injured himself in training, he picked up Grade-2 ligament tear of his ankle; unfortunately while rolling his ankle over the ball. He will be out for approximately 6-8 weeks, depending on recovery and so on. Those are the two main injury worries, nothing else to report really."
