via Jason LaCanfora:
Kris Brown won the kicker competition in San Diego and will be signed to fill in for Nate Kaeding while he is injured.
Kris Brown is an 11-year veteran of kicking in the NFL, having spent the last 8 years kicking for the Houston Texans. Outside of bad years in 2001 (which lost him his job in Pittsburgh) and 2009, he has been one of the league's better Kickers.
UPDATE: QB J.T. O'Sullivan has been released to get Brown onto the roster.
