Hull sign Villa keeper
The Third Division promotion hopefuls have forked out £50,000 to lure the former England Under-20 international to The Kingston Communications Stadium.
Myhill had been on loan at Stockport for the past three weeks and Sammy McIlroy was keen to sign the 21-year-old on a permanent basis.
But they have been beaten to the youngster's signature by Hull after Myhill had decided it was time to quit Villa Park in search of regular first-team football.
The American-born shot-stopper has agreed a two-year contract with The Tigers and wrapped up his move after passing a medical on Thursday afternoon.
