Thomas Frank insisted Neal Maupay and Said Benrahma missed Brentford’s pre-season win at AFC Wimbledon because of injury.
There has been speculation over the futures of both players, with reports suggesting that Sheffield United are looking to sign striker Maupay.
Aston Villa, managed by former Brentford boss Dean Smith, have been linked with both players.
But Smith’s successor Frank told West London Sport that the duo are recovering from knocks and will be assessed ahead of the squad’s trip to Austria.
“Said is still recovering from his injury in the Spring, while Neal had just a slight overload and we are checking him for Austria,” Frank said.
Frank confirmed that defender Ezri Konsa, who also missed the game, will not return to training until July 15 following his involvement for England at the recent Under-21 European Championships.
Christian Norgaard scored on his Brentford debut in a 3-0 win at Kingsmeadow, where fellow new signing Ethan Pinnock also featured.
Centre-back Pinnock – signed from Barnsley last week – started the game in a back three alongside Henrik Dalsgaard and Tom Field.
Norgaard, who joined from Fiorentina, was part of a complete line-up change at half-time that also saw Ollie Watkins introduced – and both got on the scoresheet.
B team striker Marcus Forss scored the opener when he beat two defenders and found the net inside the near post in the second half.
Norgaard turned in at the far post to make it 2-0 before Watkins, who looked sharp, completed the win with a close-range finish.
Brentford first-half (3-4-3): Daniels; Dalsgaard, Pinnock, Field; Canos, Oksanen, Sawyers, Dasilva; Coote, Shaibu, Marcondes.
Second-half (4-3-3): Gunnarsson, Clarke, Racic, Carroll, Henry; Norgaard, Dasilva, Zamburek; Hammar, Watkins, Forss.
