On Wednesday, the Niners cut Zuttah, the team announced. The team signed linebacker Sean Porter in a corresponding move.
"That was a tough decision," coach Kyle Shanahan told reporters Wednesday. "He's done a lot of good things in this league. We wanted to give him chance to go somewhere else."
The 49ers swapped sixth-round picks with the Baltimore Ravens for the rights to the 31-year-old center, moving down 12 spots for the five-month tryout. Zuttah had been working with the second- and third-team groups in training camp.
With the Ravens losing center John Urschel to retirement, it's conceivable Zuttah could return to the team with which he started 16 games and earned a Pro Bowl bid in 2016 -- if Ozzie Newsome can do some salary-cap maneuvering.
