Lancashire have completed the controversial signing of England seamer Ajmal Shahzad.
Earlier this month, Yorkshire confirmed that the 26-year-old was free to find another county.
Shahzad, who has made 12 appearances for England including a single Test, has now become this first player to move between the rival rose counties since David Byas in 2002.
Following Yorkshire's relegation, the pair are not due to play each other until the Friends Life t20 fixture at Headingley on 29 June.
