Hibs have bolstered their midfield options by signing Stephen McGinn on a deal until the end of the season.
The 31-year-old has been training with the Easter Road side since the squad returned for pre-season training in July, and has also been involved in the coaching side of things.
He follows in the footsteps of younger brothers Paul, an ever-present in the Capital club’s defence this season, and John who helped Hibs to Scottish Cup glory and the Scottish Championship title before earning a move to Aston Villa.
Speaking to the club's website, McGinn said: “It means a lot to me to have signed for Hibernian and it goes without saying that no-one needs to explain the size of the club to me.
“John and Paul have thrived here and it’s a privilege to get the chance to play my part as well.”
As well as playing under him at St Mirren, the versatile midfielder lined up alongside Ross at the Buddies as a youngster, and has also turned out for Watford, Shrewsbury Town, Sheffield United, Dundee, and Wycombe Wanderers in a 14-year career to date.
Ross added: “For me, Stephen adds a lot to the group and the environment at HTC.
“You can never have enough good professionals with leadership qualities and we’re fortunate, as I’ve said repeatedly, to have a great core of those at Hibernian."
Speaking earlier this season about the coaching role played by McGinn during matchdays, Ross explained: “He’s watched the games from up in the stand, feeding information down to the bench.
“It gives us another vantage point. I like it, I’ve used it in the last three or four seasons – I think it benefits me as a manager and the staff as a whole.
“I had a really good relationship with Stephen when he was my captain but it’s not a sympathy vote. He’s doing it because he adds value.
“He is someone whose contribution, input, and knowledge of the game I very much trust, and he’s helped my staff and I over the opening three league games by being part of that.
“It’s been a great learning experience for him – but great for me, because he’s helped us win these games.”
