Scotland international Sean Maitland will join London Irish next season.
Maitland, who signed for the Warriors in October 2012, has made 38 appearances for the club and has scored 11 tries during his spell in Glasgow.
The 26-year-old winger has 15 caps and 2 tries for Scotland.
Glasgow Warriors head coach Gregor Townsend said: “Sean has played a big role at the club over the last 3 years and we wish him all the best when he leaves at the end of the season.
“There is still a lot of rugby to be played between now and then and I’m sure he’ll want to leave the club on a high in the summer.”
Duncan Weir has been ruled out of this year’s Six Nations tournament with the 23-year-old set to undergo surgery on his arm.
The Glasgow Warriors flyhalf, who gave Scotland a last-gasp victory over Italy in last year’s competition, took a knock on his arm during the 1872 Cup clash with Edinburgh at Scotstoun last month, with subsequent examination showing that he had severely damaged his bicep.
Warriors head coach Gregor Townsend said that the injury suggested that Weir would be out of international action for the next three months.
Townsend added: “I would like to think it won’t be the end of his season, but I think it rules out the Six Nations.
“With a bicep injury you are talking months rather than weeks.”
Richie Vernon will start at outside centre for Glasgow Warriors, when they host French Top 14 side Toulouse at Scotstoun Stadium tomorrow lunchtime (kick-off 13:00 BST, 15:00 SA Time).
Vernon impressed from the bench in the narrow 19-11 defeat at the Stade Ernest Wallon on Sunday and replaces Peter Horne for the European Rugby Champions Cup encounter, with Alex Dunbar moving to inside centre.
There are two other personnel changes with Tim Swinson coming in for Leone Nakarawa in the second-row and Ryan Wilson replacing the injured Chris Fusaro in the backrow. Wilson starts on the blindside, with Rob Harley moving to openside.
Edinburgh head coach Alan Solomons believes that his squad has got through the worst of an injury crisis which threatened to engulf the team just a few short weeks ago.
Edinburgh flew to Milan yesterday then took a 75-mile bus ride to Parma, ahead of facing Guinness Pro12 strugglers Zebre at the Stadio XXV Aprile tomorrow afternoon.
It may have been an arduous trip but Solomons was in good fettle – despite Edinburgh still being without several leading players, including Grant Gilchrist (broken arm), Hamish Watson (knee) and Cornell du Preez, who is set to miss the rest of the season with a leg injury.
Solomons said that the Autumn Tests came at just the right time for other leading players to recover and he is excited about his team’s chances of climbing into the top six of the Pro 12 table, which would qualify them for the Champions Cup next season.
Edinburgh returned to action in fine style last Sunday when they defeated Cardiff Blues at home, and they will fancy their chances against a Zebre side which was hammered 43-3 by Connacht on Friday night.
Having been involved in the professional game for the best part of 20 years now, I fully appreciate the hard work that goes in on a daily basis for players to perform and the challenges they face mentally and physically throughout the season.
Since becoming a coach, I also know the hours, which all those that support the players put in behind the scenes, whether they are coaches, medics or performance staff. However, I reckon that the toughest job in professional rugby might not be that of the players or management, but that of our referees.
The game’s officials often perform a thankless task and don’t get the chance to share a victory with others like we do. And, in the context of our fast-moving collision-based sport, which has a number of intricate laws, it is very difficult to get everything right.
Coaches and players make many mistakes during 80 minutes of rugby, so it is understandable that referees will also make errors. A lot of these errors are frequently viewed as great decisions by the opposing team, which makes things even more difficult for the man in the middle to get things right.
Gregor Townsend has named a 26-man squad for Saturday’s pre-season friendly against Aviva Premiership side Harlequins at Scotstoun (ko 15:30 BST / 16:30 SA Time).

Glasgow Warriors will host Harlequins in a pre-season friendly at Scotstoun Stadium on Saturday 23 August, kick-off 15:30 BST.
