The 49ers released Hightower on Friday, Ian Rapoport of NFL Network reports.

EDGE Analysis

Early in training camp, there were some inklings that Hightower was vying for reps with the first-team offense over Carlos Hyde, but the cream rose to the top throughout the preseason, leaving Hyde in his expected role and the top reserve RB spot to undrafted free agent Matt Breida. At 31 years of age, Hightower may be reaching the end of the line as a viable professional.
