Brentford's search for a new striker is unlikely to be completed in time to face Wolves at the weekend.
Manager Mark Warburton has been in the market for another frontman since Chuba Akpom returned to Arsenal last week.
The Bees boss had been hopeful of adding to his fiirepower ahead of the visit of Kenny Jackett's men, with former loanees Conor McAleny and Kadeem Harris believed to be on his radar.
However, Warburton admits they are no nearer to bringing in reinforcements.
He said: "We are looking at someone, but these things take time and we have to respect the wishes of the parent club.
"We might get a call to say they will be available next week, but we've got a couple of options."
