Shrewsbury Town have extended midfielder Nicky Wroe's loan from Preston North End until 1 January.
But they have lost the services of fellow loan man Cristian Lopez, 24, who has been called back by his injury-hit parent club Huddersfield Town.
Shrewsbury have also been hit by an injury blow to left-back Joe Jacobson.
The scorer of Town's opening goal in Saturday's 2-0 win over Sheffield United has been ruled out for three weeks with a hamstring problem.
But the extension of 28-year-old Wroe's loan, just 11 days after he initially returned to his old club for a month, is a big plus for Town boss Graham Turner.
"Nicky Wroe is a combative midfielder who knows what the game's all about," Turner told BBC Radio Shropshire.
"He's powerful, he gets in the opponents' box, and he can score goals.
"It's been relatively easy for him to come back here and go into the side."
Wroe has been made available by Preston for this Saturday's FA Cup first round tie at League One rivals Walsall, but Town have had no such luck with regard to two of their three other loan players.
Wolves have refused permission for young Irish striker Liam McAlinden, who is on loan until January, to play in the tie, while Lopez has already gone back to Huddersfield, having scored once in his five games.
Shrewsbury remain hopeful that Middlesbrough will allow them play to play midfielder Adam Reach at the Bescot Stadium.
