McClenahan, Cerny and Andrews will be part of Accies defence this season
Former Rangers defender Marvin Andrews has won a one-year contract with Hamilton Academical after rejecting a new deal with Raith Rovers.
Accies have also concluded the paperwork on goalkeeper Tomas Cerny's £180,000 move from Sigma Olomouc after a successful loan spell last season.
And they will extend defender Trent McClenahan's contract by a year.
The 33-year-old Andrews helped Rovers win the Division Two title last term and earned a Trinidad & Tobago recall.
It had been Andrews' third spell with the Kirkcaldy club.
Now he will return to the Scottish Premier League, which he won with Rangers in 2005, having impressed in a bounce game against Queen's Park on Monday.
Andrews left Carib in his homeland for Rovers in 1997 and moved on to Livingston three years later.
Having signed for Rangers in 2004, he famously played on without surgery through a normally career-threatening cruciate ligament injury.
Andrews said it was his Christian faith that saw him through, but the injury caught up with him when it ruled him out of Trinidad And Tobago's 2006 World Cup campaign.
That summer, he returned to Rovers but left the club by mutual consent two years later because a troublesome cartilage problem required surgery that would prevent him playing for much of the season.
However, he signed again for the club in time to play the final 10 games of their title-winning and promotion season.
Andrews won his 100th cap in June as Trinidad and Tobago lost 3-2 to Costa Rica in a World Cup qualifier.
Meanwhile, on the day midfielder James McCarthy agreed a £1.2m transfer to Wigan, Accies have finally made Cerny a permanent signing after concluding negotiations with his former Czech employers.
Cerny, who had been interesting Swansea City, has played 59 times for Accies since arriving on loan in 2007.
However, Olomouc demanded a fee after Cerny agreed a two-year contract with Accies in April.
The fee is treble the club's previous record purchases - £60,000 paid for Paul Martin from Kilmarnock in 1988 and for John McQuade from Dumbarton in 1993.
Fellow 24-year-old McClenahan, who joined Hamilton in September after leaving Hereford, has won a new contract after playing 24 times last season.
McClenahan returned to his native Australia in May for an operation and Accies say he will put pen to paper when he arrives back from Sydney on Wednesday.
