Kyle Edmund hopes he will have recovered from a hip injury in time to feature for Great Britain in their Davis Cup first-round tie against Spain.
The 23-year-old British number two picked up the problem during his Australian Open semi-final defeat to Marin Cilic last Thursday.
"My body has a few niggles and I'm taking it one day at a time," he said.
"The transition from any surface to clay is not an easy one. My intention is to play as I love Davis Cup and representing my country."
Edmund was part of the British team that won the Davis Cup in 2015 and much will be expected of him in the absence of the injured Andy Murray.
Great Britain captain Leon Smith said: "Hopefully he can play but if he doesn't it gives younger players an opportunity to go and get a great experience.
"We're just going to wait and see how he wakes up on Thursday morning. If he feels good we'll discuss it, if not others will get an opportunity."
Cameron Norrie, Liam Broady, Jamie Murray and Dominic Inglot are also in the squad.
Great Britain are 1000/1 to win the 2018 Davis Cup outright, while Spain can be backed at 1000/1 and defending champions France at 12/1.
