"I'm really looking forward to joining Northamptonshire and getting to play in the County Championship." Nair said in a statement. "You hear a lot about county cricket and I know Prithvi [Shaw] really enjoyed his time with the team so it's exciting to have the opportunity to be involved too.

"Hopefully I can make an impact for the team while I'm there, that's the main thing for me. It's about doing as much as I can to help the team get some wins in these last three games."

Nair had arrived in the UK on Friday and will link up with the Northamptonshire side ahead of their game against Warwickshire, which begins on Sunday.

Head coach John Sadler welcomed Nair into the Northamptonshire set-up.

"It's great that we've been able to secure Karun to come over for the remainder of the season, he's really keen to get going." Sadler said. "He's a high class batter who's scored something like 11,000 runs in his career and his first class numbers are particularly special."
