ST. LOUIS -- St. Louis Blues forward Robert Thomas will miss at least six weeks with a broken right ankle, the team announced Wednesday.

The Blues put Thomas on injured reserve after he took a puck off the ankle early in the third period of their loss Tuesday night to still-unbeaten Winnipeg. General manager Doug Armstrong said Thomas would be evaluated in six weeks.

Thomas is the latest St. Louis player to get knocked out of the lineup. Defenseman Nick Leddy landed on IR earlier this week because of a lower-body injury.

The Blues opened the season 4-3-0 without Torey Krug and others available. Krug will miss the entire season after undergoing ankle surgery.

St. Louis also this week signed defenseman Jake Neighbours to a two-year extension worth $7.5 million. Neighbours will count $3.75 million against the salary cap for the 2025-26 and 2026-27 NHL seasons.
