Scotland have announced that Glen Young, Jamie Bhatti and Hamish Watson have all dropped out of the squad ahead of next weekend's clash with Ireland in Dublin - with the first two missing out through injury. 

The trio haven't been part of a single match day 23 for Scotland during the Six Nations campaign and they won't add to their international honours in Dublin either after being released from the squad.

Ally Miller has been called up as a replacement while Glasgow Warriors youngsters Alex Samuel and Max Williamson are also training with the squad. 

Watson wasn't in the original Scotland squad but was called in during the tournament but the 59-times capped flanker is one of three to drop out along with his Edinburgh team-mate Young. 

The former Harlequins lock has picked up three caps for his country while the other player to drop out is Glasgow prop Bhatti, who has 32 international caps but has fallen behind Alec Hepburn as deputy loosehead prop to Pierre Schoeman this campaign.

Gregor Townsend has called up uncapped Miller, who though uncapped at senior level, has played for Scotland at age-grade and on the Sevens circuit.

Townsend is under pressure with Scotland having lost in Italy and they face the prospect of having won just two of their Six Nations games at a time when many feel they should be challenging for the championship. 

Second row pair Samuel and Williamson are also added to the training squad and will help Scotland prepare for Saturday's game. 

The pair, both 21, have been impressing for the Warriors under Franco Smith and started recent games against Dragons and Benetton.
