Broberg sustained a lower-body injury and won't return to Saturday's game versus the Panthers, Alex Ferrario of 101 ESPN reports.
Broberg was ruled out pretty quickly after leaving the contest, which could be a bad sign. His absence also came at a time when the Blues were behind 4-0, making it unlikely they'd risk putting him back in. Either way, fantasy managers will have to wait for a further update from the team to determine Broberg's availability for Tuesday's game versus the Ducks.
