Jimmy Smith will announce his retirement with the Baltimore Ravens on Monday.
There is a news conference on Monday.
Smith will forever be remembered for stopping Michael Crabtree from making a catch on a fourth-down, goal-line stand, which preserved the Ravens' 34-31 Super Bowl win over the San Francisco 49ers.
49ers fans accused Smith of holding the receiver in the end zone.
Smith said the title was the only thing he had. He has a Super Bowl ring tattooed on his arm.
Smith was drafted by the Ravens in the first round. Smith was known for his size and ability to shut down top wide receiver.
He wasn't able to reach a Pro Bowl due to injuries. He didn't miss a game in his career.
Smith indicated at the end of last season that he was going to retire.
I wonder if I want to put my body through this again. Smith made the statement last year. These last games are important to me. I'm not young anymore. I've been through many injuries and they pile up on you.
