Niners weren't banking on Johnson

Posted by ESPN.com's Mike Sando

The Bryant Johnson experiment in San Francisco unofficially ended when the 49ers showed little concern in letting the receiver hit free agency after one injury-affected season with the team. The official end came Saturday when Johnson agreed to terms on a three-year, $9 million deal with the Lions.

Johnson wound up getting a raise from the $2 million salary he earned from the 49ers last season. The 49ers' acquisition of Brandon Jones from the Titans fills Johnson's roster spot, but San Francisco is not finished making over the position. Isaac Bruce's decision on retirement could also affect the 49ers' plans.
