The productive ten-year career of Jamal Lewis has met an unfortunate ending.

The Browns placed Lewis on season-ending injured reserve Wednesday because of post concussion symptoms. Lewis has stated repeatedly he plans to retire at the end of the season.

Safety Brodney Pool was also placed on I.R. because of a concussion. The team filled one roster spot by claiming former "Mr. Irrelevant" Ramzee Robinson off waivers.
