Striker Lee Tomlin has signed a three-and-a-half year contract for Middlesbrough FC after having his loan from Peterborough United changed into a permanent transfer.
The fee is as yet undisclosed.
The 25-year-old initially joined from the Sky Bet League One club for the remainder of the season on transfer deadline day.
Tomlin signed for Peterborough from Rushden and Diamonds in August 2010 after scoring 28 goals in 169 appearances for the Northamptonshire side.
After completing a three-match suspension last weekend, Tomlin is eligible for selection to make his Boro debut in Saturday’s game against Leeds United at the Riverside.
