Bristol Rovers manager Paul Buckle has brought in Hungarian international Krisztian Timar on trial.
The 31-year-old former Plymouth Argyle defender featured in a reserve game for the Pirates earlier this week.
"He's 6ft 3in, he's experienced and he can head the ball," Buckle told BBC Radio Bristol.
"Some of our centre-halves are not blessed with height so I've looked at Timar and I'll give myself 24 hours on that before making a decision."
Timar has not played in English football since his release from Plymouth at the end of last season.
He made 91 appearances during his four-year spell with the Pilgrims and also spent time on loan at Oldham, where he played two games.
