Middlesbrough boss Aitor Karanka in no rush with Socceroos star Rhys Williams and winger Muzzy Carayol

Williams has not played since damaging his Achilles tendon in January’s draw with Wigan.

The Australia defender has suffered a niggle in training, though Karanka is not concerned, while Carayol is doing light work at Rockliffe after recovering from a cruciate ligament at Bournemouth in March.

“Rhys is a long-term injury and Muzzy is going very well but Rhys had a set-back this week and had to rest, but it’s nothing major,” Karanka told www.mfc.co.uk. “When you’ve been out for 10 months, one more week out doesn’t matter.”
