The former Scotland striker, who made seven appearances for his country, has lived a somewhat itinerant existence in recent years, having been on the books of Hearts, St Johnstone, Barnet and now Dundee in the past two seasons.
His most recent move has caused the striker to drop into the SPFL Championship but John Brown is confident that his latest acquisition will run amok, should he maintain his fitness. Injuries disturbed his time at St Johnstone and was also a concern for clubs during previous trial spells in the summer.
"I really believe in the player," said the Dundee manager. "A fit Craig Beattie will cause havoc for our opponents all season."
