RALPH Hasenhuttl admits he is unsure how serious Armando Broja’s injury is but confirmed it was a hit to the top of his knee, leaving the boss hoping Saints have not paid a “high price” for FA Cup progression.

His side were forced into another extra time to defeat Championship opposition in Coventry City, as the bodies racked up before a 2-1 victory.

Lyanco had been subbed earlier in the match after he picked up a hamstring injury which Hasenhuttl has described as looking “very serious”.

Saints face Spurs and Manchester United in the next seven days and could have done without the additional time, not to mention two potentially serious concerns.

Speaking after the match, Hasenhuttl said: “Not good.

“Hopefully we have not paid a too high price for going in the next round but there are no easy games around. We tried to manage everyone with gametime but it is not so easy.

“The injury to Lyanco looks very serious, it was also a problem because we had no other subs.”

He continued: “Players had to play longer than they should play, Tino for example his first game back and nearly 90 minutes, after 60 normally he should be finished.

“In an FA Cup game you cannot control what happens and against a team that is so tough.”

On Broja, he added: “He was fouled on the middle line and it was a hit on the top of the knee and we must look how serious it is. But hopefully not too serious.”
