This from the San Francisco Chronicle:
Top return man Allen Rossum was released by the San Francisco 49ers on Monday, creating roster room for newly signed rookie receiver Michael Crabtree.
Rossum was surprised by the move when summoned to a meeting with coach Mike Singletary. He also spoke with general manager Scot McCloughan.
The 33-year-old player ranks second in league history with 14,987 return yards. He hadn’t been active the past two games after playing in the first three to start his second season with the 49ers.
