The 32-year-old surpassed former Rotherham forward Shaun Goater’s tally of 18 outings for Trinidad and Tobago when he completed 90 minutes against Kazakhstan at the weekend.
Arnason now holds the record for the most international appearances made by a Rotherham United player having made 19 in major competitions, and 37 when including friendly fixtures.
Despite serving a suspension on Good Friday, Millers boss Steve Evans was happy to have the Icelandic international back at the club and ready for Sky Bet Championship action:
“Kari played in the European qualifier and got a great result away at Kazakhstan,” he beamed.
“He was on the bench in midweek and not used which was brilliant for us because Lars has kept to his wordwhen he said if he didn’t have to use Kari in the second of the matches he wouldn’t do so.
“We’re pleased both Kari and Danny Lafferty come back invigorated and with both of their countries doing well."
