Flowers left Sunday's game with what the Chiefs called a hamstring injury. Kent Babb of the KC Star reports Flowers did not practice on Wednesday for the start of KC's preparation for the Seattle Seahawks. We're not sure what the injury or how severe it is or if it's just a day of rest for Flowers.
Losing Flowers for any stretch of time would be a blow to the Chiefs but I'll go out on a limb here and say they could handle missing him on Sunday. The Seahawks aren't a huge threat offensively so, if he were to miss anytime, it would ideally be against the Seahawks and not the following two weeks against the pass-heavy Denver Broncos and San Diego Chargers.
We're also awaiting injury news on TE Tony Moeaki, S Jon McGraw, LT Brandon Albert and WR Dexter McCluster. The Star has more practice info here.
