Chelsea will reportedly wait until further medical checks on Monday before making a decision over the signing of Leicester City defender Ben Chilwell.
With Frank Lampard looking to make changes at left-back, Chilwell is on the brink of a big-money switch to Stamford Bridge.
However, despite an announcement said to be imminent, The Sun claims that the England international must first come through a further medical with a specialist on Monday.
At a time when he is continuing to recover from a heel injury, there are allegedly concerns that the 23-year-old could be sidelined for another six weeks.
If that proves to be the case, the report says that Chelsea may have second thoughts about finalising a £50m deal for the player.
Chilwell was ruled out of Leicester's final five Premier League games of the most recent campaign due to the same issue.
