Hemingway left Sunday's practice with a back injury, the Kansas City Star reports.

Analysis:

Once he returns to action, Hemingway, who caught 12 passes for 108 yards in 14 games last season, will jostle with Albert Wilson, Jason Avant, De'Anthony Thomas, Chris Conley and Frankie Hammond Jr. for wideout slotting, behind the Chiefs' top option at the position, Jeremy Maclin.
