Rovers beat yesterday’s loan deadline to sign Aston Villa defender Enda Stevens.
The 23-year-old Irish left back has arrived at the Keepmoat Stadium on a one- month loan deal.
He goes straight into the squad to face Queens Park Rangers tomorrow.
Stevens’ arrival is a major boost for boss Paul Dickov, whose defensive resources have been stretched to the limit with Jamie McCombe, Rob Jones and James Husband all sidelined.
Full back Reece Wabara also went for a check-up scan on the toe he fractured against Watford in September yesterday - and may now be rested following the capture of Stevens.
Stevens, who can also play at centre back, made four appearances on loan at Notts County earlier this season.
The Republic of Ireland U21 international joined Villa in January 2012 after starring for Shamrock Rovers in the League of Ireland and Europa League.
Dickov, meanwhile, leapt to the defence of Wabara whose recent performances have come in for criticism from some supporters.
“He has put his body on the line for this club when he should have been looking to rest,” said Dickov.
“Not many loan players would do that.
“I know he is not performing to his best but he is not the only one, so you cannot single any individual out.”
Fellow loan left back Yun Suk-Young could be fit again by mid-December, Dickov also revealed at yesterday’s pre-match press conference.
