Blankenship has won the Colts' kicking job with the team releasing Eddy Pineiro on Tuesday, Adam Schefter of ESPN reports.
Undrafted last year, Blankenship won the job with a strong training camp and converted 32 of 37 field-goal attempts (86.5 percent) in the regular season. However, he had just three attempts from 50-plus yards, missing two, and then missed a field goal in a playoff loss to Buffalo. Blankenship will keep his spot for Week 1, but the month-long job battle with Pineiro this summer suggests Colts brass isn't entirely sold on him.
