Bangladesh captain Mashrafe Bin Mortaza said that it was too early to say whether he will be available for the upcoming home series against Zimbabwe.Zimbabwe will arrive in Bangladesh on October 21 to compete in the five-match one-day series against the Tigers in Dhaka and Chittagong and Mashrafe has been retained as captain for the series despite the uncertainty over his fitness. The 'Narail Express' joined the national camp yesterday although he is not yet fit to perform the fitness drills as the space spearhead is going through rehabilitation programme after having his both knees operated on."It is too early to say anything on my return for the home series against Zimbabwe. I still have more than a month to get fully fit for the series. And as per surgeon's (Dr. David Young) advice, I will be available from before the second one-dayer," said Mashrafe while speaking to reporters at the Sher-e-Bangla National Stadium in Mirpur yesterday. The first match of the five-match series will take place at Mirpur on October 27 and the second and third game will be held at the same venue on October 29 and 31 respectively. The fourth and fifth one-dayers are scheduled to take place in Chittagong on November 3 and 5.“I can understand my position once I start the running in two weeks. I feel good now even though there is bit of pain at times. I may even be able to play the first one-dayer if I feel good because the surgeon said that it would be up to me to decide," said Mashrafe, who injured his right knee during the first Test against the West Indies at St. Vincent in June and has been out of the game since.National team physio Michael Henry too echoed Mashrafe's words as he said that it's very difficult for any surgeon to put a definite time frame on return.It was painful for the country's leading paceman not to be part of the team's recent successes in the tours of West Indies and Zimbabwe but he was happy with the progress of the team and said it would not be easy for him to get back to rhythm after long absence from cricket. "For any pace bowler it's not easy to get back to rhythm after recovering from injury. So, it would be a big challenge for me no matter who the opponents are. I am looking forward to returning to cricket. I may miss the T20 Premier League matches but I am hopeful about the Zimbabwe series," said a confident Mashrafe. Bangladesh skipper also expressed his satisfaction over the Bangladesh Cricket Board (BCB)'s recent decision to continue with the current set up of the national team including the extension of coach Jamie Siddons's tenure to 2011 World Cup."It's always good not to make random changes in the team. I think it's a very good decision to continue with the same coach because every coach has his own style of coaching and you must give someone enough time to shape the team by applying his method," Mashrafe concluded.
