Leeds United have been dealt a potentially huge injury blow ahead of their clash with Cardiff City this weekend.The Whites return to Championship action after more than three months as they travel to South Wales hoping to get their promotion race back on track.However according to Phil Hay, they may have to do it without Pablo Hernandez.The midfielder is reportedly a doubt for the clash with the Bluebirds due to a 'niggle' which has proved troublesome over the last couple of days.While the severity of the knock is not yet known, The Athletic's Leeds United writers says that he remains a doubt for Sunday's clash.

Phil Hay also provided an injury update on Jean-Kevin Augustin.

It was reported that the on loan striker had suffered a hamstring injury during training at Leeds United and faced a spell on the sidelines.

Hay referenced that in a reply by saying that while it needs to be confirmed, he's unlikely to be ready for the weekend.

GIVEMESPORT'S Phil Spencer says...

A double injury blow is far from ideal for Leeds United.

The upcoming games of the utmost importance to the Whites as they look to get themselves over the line and secure a return to the top flight.

Jean-Kevin Augustin's injury is disappointing, but it's nothing compared to the impact of losing Pablo Hernandez.

The midfielder is absolutely pivotal to the way that Leeds United play, and it's been proven this term that they aren't nearly as fluent on the ball without him in the side.

They'll certainly be hoping for him to be ready.
