The last time Anquan Boldin and Torrey Smith were on the field together as teammates was during Super Bowl XLVII when the Ravens beat the 49ers to win a title. They are hoping for a similar result this season -- only this time with San Francisco on top.

Boldin said Tuesday during an interview with CBSSports.com at a training session for XPE Sports that Smith will be signing with the 49ers as a free agent. He indicated the signing was imminent.

"It'll be cool, man," Boldin said of being reunited with Smith. "Me and Torrey had a great relationship in Baltimore. We continue to be friends off the field. I definitely have done some recruiting. It'll be cool having a guy like Torrey back on the field. He's a guy that can take the top off. It will help us out tremendously."

Smith is expected to replace Michael Crabtree, who is a free agent. He is leaving Baltimore because the Ravens can't afford him, and he could be paid around $8 million to $9 million annually.

Smith thanked the Ravens on his blog for his time in Baltimore, where he won the Super Bowl and also racked up 213 catches for 3,591 yards and 30 touchdowns over four seasons. He finished last year with 49 catches for 767 yards and 11 touchdowns.
