Viktor Arvidsson will be out 4-6 weeks for the Nashville Predators because of a lower-body injury.
Arvidsson was injured on a cross-check by St. Louis Blues defenseman Robert Bortuzzo at 6:04 of the first period during Nashville's 4-2 win on Saturday. The forward remained in the game before leaving at 10:11 of the first.
Bortuzzo, who was assessed a minor penalty for cross-checking, will have a hearing with the NHL Department of Player Safety on Sunday.
Arvidsson has 15 points (six goals, nine assists) in 22 games this season.
Nashville (10-9-3) hosts St. Louis at Bridgestone Arena on Monday (8 p.m. ET; ESPN+, FS-TN, FS-SW, NHL.TV).
