Swansea City manager Carlos Carvalhal fears that Leon Britton and Angel Rangel will miss the FA Cup fourth-round replay against Notts County.
The Swans had been dealt two major blows at the weekend when Leroy Fer and Wilfried Bony suffered season-ending injuries at Leicester City but Carvalhal now faces the prospect of having two more players being sidelined.
Fer has ruptured his Achilles tendon while Bony tore his anterior cruciate ligament.
Carvalhal admitted: "Two players have some issues, we are analysing them. It is Leon (Britton) and Angel (Rangel). They have been training but with limitations so we are assessing them. They are training, and then stop, then training, then stop.
"We have no problems other than the situations of Renato [Sanches], Fer and Bony."
Meanwhile, former Sheffield Wednesday boss Carvalhal insists it will not be a disaster if the Swans are beaten by Notts County as survival in the Premier League remains his number one priority, adding: "Staying in the Premier League of course, this is the most important thing for the club.
"I am experienced enough in English football to know it won't be easy [against Notts County]. These teams ask questions Premier League teams don't put to you so we have to be ready for the right answers."
Swansea, 1/2000 to be relegated this season, can be backed at 9/1 to beat Kevin Nolan's Notts County side 3-0 on Tuesday.
