The 49ers have added another player well-versed in Kyle Shanahan's system -- running back Tim Hightower, who played in Shanahan's Washington offense in 2011 and who agreed to terms on a contract with the 49ers on Saturday.
The announcement was made on Twitter by general manager John Lynch, who already has shown a comfort level with media sessions, radio hits and social media his predecessor, Trent Baalke, was missing.
Hightower, 30, will compete for a role behind tailback Carlos Hyde with DuJuan Harris, Mike Davis and Raheem Mostert. Hightower (6-0, 220) spent three years recovering from an ACL tear and subsequent infection, but had a comeback in 2015 with the Saints and gained 923 yards as a backup the last two seasons.
