In a closely contested game against the Jaguars, Joe Flacco showcased his quarterbacking skills, completing 33 of 44 passes for 359 yards, three touchdowns, and no interceptions. Despite the Colts' 37-34 loss, Flacco's performance highlighted his ability to deliver strong numbers in a starting role, especially in the second half where he connected with multiple targets for scoring plays. His performance raises questions about the starting position for the upcoming week, given the uncertainty surrounding Anthony Richardson's health.

• Flacco proved he can deliver starter-quality production.
• His performance may influence the Colts' decision on the starting QB for Week 6.
