49ers bring back guard Al Netter

The San Francisco 49ers have filled their 90-man roster by re-signing guard Al Netter on Monday.

Netter, who was released earlier this offseason, was on the 49ers' practice squad for all of the 2012 season and for the final three months of last season. He will compete for a roster spot in training camp.

The 49ers had an opening on the roster because of cornerback Eric Wright's recent retirement.
