West Bromwich Albion boss Alan Irvine is expected to hold onto Liam O'Brien, rather than allow him to leave on-loan.
O'Neil has regularly featured as a travelling reserve in the last few Premier League matches and could be given another opportunity in the next round of the League Cup at Bournemouth on Tuesday week.
"Liam has shown how well he can cope," Irvine told the Birmingham Mail. "He was in the squad again for the Burnley match and with the performance he had against Hull you are thinking 'You have done enough to be in and around the squad'.
"He would be a difficult one, whether or not we want Liam to go on loan - that's another matter."
