The 28-year-old – capped 15 times by Wales – made his international debut in the 49-11 victory over Zimbabwe in the nation's Africa tour of 1998.
The former Neath favourite was a standout performer in Swansea's impressive run to the quarter-final of the European Cup in 2001 and their charge to the domestic title in the same season.
His form during that season saw him selected for the Lions tour of Australia in 2001 and he was extremely unlucky not to get a Test start in the No.1 shirt given his form during the tour, although he did make the bench for the third Test against the Wallabies.
But since that highpoint, Morris' international career has stalled, with the heavyweight prop falling out of favour with the current Welsh management who have voiced concerns over the front rower's perceived lack of fitness.
Indeed, just last year Morris was told to 'shape up or ship out' by the then Swansea coach John Connolly, leading to speculation over the prop's future and earlier this year he was linked with a move to South African Currie Cup side, the Natal Sharks.
The versatile Morris can play at either tighthead or loosehead, making him a valuable addition to the Tigers front row reserves which have been depleted by the losses of Franck Tournaire, Perry Freshwater and Darren Garforth.
