Former Newcastle United defender David Edgar was on trial at Sunderland last week.
The 31-year-old, who started his professional club football career at Newcastle, is a free agent at the moment following his departure from Ottawa Fury.
The Canada international defender was on a trial at Sunderland last week, but the League One club have decided not to offer the former Birmingham City man a contract.
Ross told The Sunderland Echo about Edgar: “He came in last week and trained. There’s nothing we’ll pursue on that.
“He did fine when he was in, we’re just looking at how we can improve and strengthen what we have.
“I’ve said previously I’m not in any desperate rush. There’s a couple of areas we’re looking at but the squad as it stands is not too bad.”
Challenging for promotion
Sunderland are going strong in League One at the moment and are aiming to win automatic promotion to the Championship.
The Black Cats are currently third in the standings with 43 points from 20 matches, five points behind leaders Portsmouth.
Sunderland will return to action on Saturday afternoon when they take on Portsmouth away from home in League One.
It promises to be a hugely exciting and entertaining game of football, and there should be a few goals at Fratton Park.
Sunderland will head into the match against Portsmouth on the back of a 2-1 victory over Bristol City at the Stadium of Light in League One.
