Undrafted free agent LeRoy Vann was the only 49ers player to return punts during last week’s minicamp.
Sixth-rounder Kyle Williams pulled a hamstring, and Ted Ginn is concentrating on receiver duties. Vann set an NCAA record with 11 combined TD returns at Florida A&M, becoming just one of five players in history to return both punts and kickoffs for at least 1,000 yards. He has a legit chance to make the team this year.
