Sheffield United beat the transfer deadline to sign Hamilton Academical striker Ryan One.
The teenager was the subject of a failed bid by Brighton earlier in the window, but join the Blades before the end of the deadline.
One, 17, has been a first team squad regular with the Scottish League One side since making his debut last year.
He made 21 appearances for Hamilton after making his breakthrough last season, scoring two goals.
Including the winner in the SPFL Trust Trophy semi-final against Queen of the South on route to Hamilton winning the competition.
