World champion Gerwyn Price has been ruled out of the Unibet Premier League after testing positive for Covid-19 and will be replaced in the field by James Wade.
All players and officials involved in the tournament were tested upon arrival at Milton Keynes' Marshall Arena on Sunday ahead of the 17-night tournament.
'The Iceman' returned a positive result, and as such will now return home to Markham to enter a period of self-isolation in line with government guidelines, the PDC announced.
UK Open champion Wade replaces Price in the field, as the Machine is the highest-ranked player in the PDC Order of Merit not to have been included in the 10-strong line-up.
Wade was in Milton Keynes on stand-by and will slot in directly for the Welshman.
All other players and officials tested on Sunday returned negative test results.
Winner of the tournament in 2009, Wade will now take on Gary Anderson in Easter Monday's opening fixtures, before playing Rob Cross on Tuesday.
The action gets underway on Monday evening from 7pm on Sky Sports Action.
Wade: 'I know I'm good enough to win it'
Despite the late call-up, the world No 4 feels he has what it takes to succeed in the competition.
"I know what I'm capable of. I haven't touched a dart since the last time I played. But I'm not a prolific practice person. So hopefully that won't make much of a difference. And after a game or two, I should be back into the swing of things," Wade told the PDC.
"But I know I'm good enough to win it. So do the other nine people unfortunately. I'll have a good go, I'm pretty sure."
Wade is appearing in the Premier League for an 11th season. Only Phil Taylor and Raymond van Barneveld featured in more campaigns.
However, the 2021 tournament will be different with games packed close together, rather than the traditional Thursday night format. Wade sees an opportunity in the new structure.
"If you start off well, you should have a bit of momentum behind you with the games close to each other," he noted.
"If you don't start off strong, that might be the same snowball effect as well. We'll see. There's not much I haven't experienced in the world of darts, so I'm pretty sure me and everyone else will adapt to it just fine and we'll see what happens."
