Scotland have reshaped their Six Nations lineup for Saturday's pivotal match against Ireland, with Gregor Townsend making three key adjustments. Max Williamson and Grant Gilchrist are promoted to the second row to address injuries to Gregor Brown and Scott Cummings, while Zander Fagerson starts at tighthead prop after a standout performance as a substitute against France. The changes come as Scotland aim to secure their first title since the competition expanded in 2000, currently level on points with leaders France.

Gilchrist, 35, is poised to win his 88th cap, surpassing Rugby World Cup legend Scott Hastings as Scotland's most-capped second-row forward. Fagerson's promotion to the starting XV highlights his growing influence, having previously shone in the 50-40 thriller against France. The Glasgow trio of Matt Fagerson, Rory Darge, and Jack Dempsey retain their back-row positions, maintaining continuity despite the front-row shakeup.

Ireland and France remain title contenders, with Paris needing a bonus-point win over England to clinch the trophy. Scotland's Darcy Graham continues his historic try-scoring run, now leading the nation's all-time list. With Edinburgh's Gilchrist and Fagerson anchoring the pack, Townsend's tactical tweaks could prove decisive in the Dublin showdown.

Six Nations permutations hinge on Saturday's results, as France, Scotland, and Ireland vie for supremacy. A Scottish victory would tighten the race, while Ireland's performance against their rivals could seal their path to glory. The final weekend will determine the 2024 Six Nations champion.
