The veteran central defender played only once this season for Steve Kean’s men due to consistent knee injuries, and was deemed surplus to requirements at Ewood Park.
Nelsen’s addition comes due to Sebastian Bassong being sent out on loan to Wolves, and the news was released on Spurs’ official website.
“We are delighted to announce the signing of defender Ryan Nelsen. The New Zealand international joins us from Blackburn Rovers where he spent seven years and made over 200 appearances,” the brief statement reads.
Tottenham assistant Kevin Bond has confirmed that Nelsen has no injury concerns at present, and will be in contention to face Liverpool at Anfield on Monday night.
“He is fit and eligible to play on Monday. I’ve just had a cup of tea with him in the canteen. He is looking forward to the challenge,” Bond told Sky Sports.
Nelsen’s signing comes as something of a surprise, but the veteran will provide cover for Ledley King, William Gallas and Michael Dawson, who have all spent time on the sidelines this term due to injury.
Meanwhile, Spurs have injury concerns over Jermain Defoe and Aaron Lennon ahead of the trip to Merseyside, with Bond admitting the England international duo were unlikely to feature after picking up knocks against Wigan in midweek.
“Aaron and Jermain are being treated, both are extremely doubtful for Monday but obviously we’ll give them every chance. The medical staff are working hard to see if they can get them there.
“Rafa [Van der Vaart] went off with a calf strain and it’s a bit early to say what his prospects are for Monday. Kyle Walker should be fine,” the assistant concluded.
