Horn is reportedly dealing with a calf injury and was limited in practice on Wednesday due to the injury. Horn presumably went into the Panthers' Week 11 bye at full health, so it's possible this is a minor injury he suffered during the team's bye week. Barring any setbacks, it sounds like the team is expecting to see him in this week's game against the Chiefs.
Carolina Panthers cornerback Jaycee Horn locked down his receivers on 90.9% of his opportunities in Week 9.
