Former England batsman Kevin Pietersen says Monday's auction for the Indian Premier League Twenty20 competition was "another slap in Test cricket's face".
Pietersen has not played an international match since he was sacked by England in 2014.
He has since become a T20 specialist and played in competitions in Australia, India, South Africa, the West Indies and in the Pakistani T20 tournament held in the UAE.
39-year-old Pietersen said on social media, "I embraced [T20] eight years ago and it's what caused me my P45, I absolutely love how all these youngsters are now benefiting.
"I love how T20 is growing the game. I'm just saying that Tests are falling way behind at the moment. The ICC [International Cricket Council] needs to act and quick."
"I'm looking forward to getting out there and getting involved."
