Shrewsbury Town boss Steve Cotterill has taken his January transfer window signings to four by bringing in two new defenders on deadline day.
Relegation-threatened Town have signed Sunderland's Tom Flanagan, 30, on a two-and-half-year deal and Newcastle's Matthew Bondswell, 19, on loan.
They follow two loan men, Bristol City striker Saikou Janneh and Nottingham Forest midfielder Tyrese Fornah.
Cotterill's side lie 16th in League One, four points clear of trouble.
Both are eligible to make their Town debut in Saturday's key home game with fellow strugglers Fleetwood.
