Luton Town manager Rob Edwards admits the absence of Albert Sambi Lokonga will hurt his team.
The Arsenal loanee will be absent for around two months with a hamstring injury.
The 23-year-old sustained the problem in the 1-1 draw with Wolves in the Premier League at the weekend.
Speaking with reporters, Edwards said: Sambi made a real positive start to his life at Luton Town, two real good performances so it's a real shame for him first and foremost as he wanted to come and perform, play games.
He was going to have the opportunity to do that with us and it's a real shame to be missing him now for a period of time.
It could be a while, we'll have to see.
"We're disappointed for him as he made a great start and he's a really good player.
