News: Staley (knee) is probable for Sunday's game against Arizona.
Impact: Staley's presence Sunday is reassuring for Frank Gore and the San Francisco passing game. He practiced fully Thursday and Friday, so Staley should be at full strength.

News: Staley (knee) was a limited participant in practice Wednesday, CSN Bay Area reports.
Impact: Staley sustained a knee injury last week, but it doesn't seem to be a serious one. His participation in practice today and Friday will paint a better picture of his availability for Sunday's tilt against Arizona.
