Warriors trio Alex Grove, Jack Cosgrove and Ben Vellacott will all be in international action for Scotland this weekend.
Grove will line-up at centre as the Scotland A side take on England Saxons at Scotstoun Stadium tonight.
Scotland will be looking for their third consecutive win over the English after victories in 2012 and 2013.
Grove, who signed a new Warriors contract in December, starred in both of those matches and will be looking to help his country to a hat-trick of wins when the match gets underway at 7.30pm.
Cosgrove and Vellacott will both start on the bench as the Scotland Under 20 side travel to Ireland in their opening Six Nations game tonight (kick-off 7.05pm.)
Academy prop Cosgrove made his Warriors debut as a replacement against Sale Sharks last Saturday and has impressed for the Cavaliers this season.
Hartpury College student Vellacott, who has also represented his country at Under 17 and 18 levels, regularly trains with the Warriors academy and has appeared for the Cavaliers this season.
