Pat MacArthur, the former Scotland age-group inter-nationalist, has signed a contract extension with Glasgow Warriors until May 2016.

He follows Al Kellock, Tom Ryder, Tommy Seymour, Peter Murchie and fellow front-row Mike Cusack in committing to Glasgow, and said: "I'm really pleased. It's great playing my rugby here and it's great to be part of this squad. It's about working together and getting success with this team.

"We are all pushing each other to get [become] better as players and I'm no different. There is terrific competition for the No.2 shirt with Dougie [Hall] and Fin [Gillies] but it's about making the team as strong as it can be."

Gregor Townsend, the Warriors coach, will today name his side for tomorrow's RaboDirect PRO12 game against Benetton Treviso at Scotstoun.

Meanwhile, Joe Schmidt, coach of the European champions Leinster, admitted to being wary of Edinburgh ahead of tomorrow's meeting between the sides at Murrayfield.

"We know from experience how difficult it is to win against them in Edinburgh," he said. "A lot of our players have played under their coach Michael Bradley at different levels for Connacht, the Wolfhounds or with the Ireland senior squad, and all speak highly of him. Edinburgh will be keen to get back to winning ways after their narrow defeats to the Warriors over the Christmas period. They showed real character to come back and almost snatch the win last weekend after Glasgow got away to a flying start.

"Games between ourselves and Edinburgh are always tight affairs. We narrowly beat them earlier in the campaign in the RDS [22-16] and it was nip-and-tuck last season over in Murrayfield when we managed to come out on the right side of a contest [36-28] that see-sawed right up until the finish.

"They have a big abrasive set of forwards and proven international performers throughout. With a player like Tim Visser in their ranks, who is racing clear at the top of the try-scoring charts again this year, we can't afford any defensive lapses."
