Kristick was undrafted this year but signed with the team and took part in training camp. He was a two-year starter at Oregon State and was named first team all-Pac-10 as a senior.
Niners coach Mike Singletary has spoken of the need to add an inside linebacker to the roster, but when Kristick's name was mentioned in the past, he said Kristick was not ready.
In another move, the 49ers announced the hiring of Chris Beake as offensive assistant coach. Beake spent the past two seasons on the staff of the Seattle Seahawks but worked previously for the 49ers from 1998 to 2003. He was an offensive assistant in 2003.
