Wouldn't say injured but definitely restricted. So much taping on his elbow, his serve is pretty much non-existent atm.
Nick has a huge future ahead of him. If injured don't play. Tell TA he can't play until 100% fit. No good losing to lower ranked players. The Pro-circuit is very competitive, there are 200 players out there who all have the potential to be top 100 players - if you take to the court injured, you will just perform poorly and give impetous to the other guy, and then start doubting your own ability.
