Former Rams center Tim Barnes will sign with Niners today, according to Jim Thomas of the St. Louis Post-Dispatch (Twitter link). Barnes visited the Niners in late April and just over one week later, he has himself a contract. 
The Rams surprised many when they cut Barnes earlier this offseason. After starting two seasons in the NFL, Barnes didn’t find a ton of interest once he hit the open market. Now he’ll join the Niners and it’s not clear whether he’ll be given a chance to compete for a starting job. Jeremy Zuttah, who was acquired via trade with the Ravens, currently projects as the team’s primary center.
In 2015, Barnes ranked as Pro Football Focus’ 29th-best center out of 39 qualifiers. This past season, PFF ranked him 31st out of 38 qualifiers.
