Wicket-keeper Dinesh Karthik has become the first player to move during the Indian Premier League 2012 trading window, switching from the Kings XI Punjab to the Mumbai Indians.
And as the franchises step up their activity during the window, Deccan Chargers' England international Kevin Pietersen has been signed by the Daredevils.
Karthik played all 14 matches last season for the Kings XI having previously represented the Delhi Daredevils, for whom he played 42 games.
"We are very pleased to add a player of Dinesh Karthik’s calibre and specific skills to the Mumbai Indians squad as this addition will further strengthen our side," Nita Ambani, owner of the Mumbai franchise, said.
Kartik has also played 23 Tests, 52 One-Day Internationals and nine T20 Internationals for his country.
Rajeev Shukla, IPL Chairman, added: "It looks like the 2012 Trading Window will be an active one as the franchises look to revise and strengthen their squads in advance of the Player Auction on 4 February 2012."
Pietersen was signed by the Royal Challengers Bangalore for the second season of the Indian Premier League before being picked up in the auction for the fourth season by the Deccan Chargers, although he did not represent them due to injury.
He captained the Bangalore side for six matches during his two seasons with them.
The trading window has been open since 15th December and will close on 20th January as teams look to build their squads ahead of the fifth season with a new limit of 33 players per squad.
