Anthony Richardson doubtful as Joe Flacco readying for potential first Colts start
Flacco, 39, took over for Richardson during the first quarter against the Steelers last week after the second-year signal-caller went down with an oblique injury, completing 16 of 26 passes for 168 yards with two touchdowns in three-plus quarters of action. The Colts won that game 27-24, delivering Pittsburgh its first loss of the season.
