Nottingham Forest striker Dexter Blackstock says he has been 'humbled' by the support he has received after his cruciate knee ligament injury.The 24-year-old, who had begun the season in fine form, could be out of action for a year after sustaining the injury at Cardiff in November. [LNB]Blackstock told BBC Radio Nottingham: "It has been very humbling how many messages of support I have had. [LNB]"It has been good for me to interact with fans and send messages back." [LNB]Blackstock was a second-half substitute in the 2-0 win at Cardiff on 20 November. and was injured moments after scoring Forest's second goal. [LNB]"I have had hundreds of messages from not only Nottingham Forest fans, but fans of other clubs, even some Derby fans have wished me well," added Blackstock. [LNB]"It's coming along very well, I am off the crutches and am very happy with how it's gone. [LNB]"I have to say a great thanks to Andy Williams who did the operation. There was a big risk that I would have to have another operation if things didn't go well, but thankfully that's not the case. [LNB]"The risks of infection are out the window now and it's just a case of moving forward. I can do work on the bike, and I can do strength work and build the muscles up around the knee [LNB]"Also I can build my upper body strength that I haven't been able to do as much when I am playing, so hopefully I come back even stronger." [LNB]Blackstock continued: "There are no set targets yet as the ligaments take as long as they need to heal and it's not a case of rushing as it's very important your knee comes back right. [LNB]"But the surgeons are very confident the levels will be the same when I come back, if not stronger, due to the amount of work I have to put in. Hopefully I will come back a better player."
