Returning to the tennis world has given Kyle Edmund that sort of weird feeling you get when you've not been somewhere for a while.
Edmund, 27, was away from the ATP Tour for almost two years because of a serious knee injury that left him wondering if he would ever return.
Three operations later, and after hours of rehab and soul-searching, the 2018 Australian Open semi-finalist is gearing up for his Grand Slam singles comeback when the US Open starts on Monday.
"It does feel a little bit like I'm starting my career all over again," said Edmund, who plays Norwegian fifth seed Casper Ruud about 18:00 BST after entering the main draw thanks to a protected injury ranking.
