Newcastle have given a trial to former Scotland number eight Ross Beattie.
Beattie has also played for Bristol, the Dragons and Northampton
The 29-year-old, a former Newcastle player, has been left without a club after the Border Reivers were disbanded at the end of the season.
"Glasgow decided not to take him on because of injury but we will review the situation in November," said Falcons boss John Fletcher.
"This allows the chance for him to state his case for a contract in the first few months of the campaign."
Beattie, who won the last of his nine Scotland caps in 2003, returns to Kingston Park six years after leaving the club for Bristol.
He has since played for Newport Gwent Dragons and Northampton whilst also featuring for Scotland in the 2003 World Cup.
"Having been away from Newcastle for a number of years people who know me will know how much it means to me to finally be back and have this chance," said Beattie.
"John Fletcher has been very open with me and we both know what the score is. My part of the bargain is to be in the best possible condition to play, and to put my case forward on the field."
