Denver signed Miami nickel cornerback Nathan Jones on Friday evening. He has three interceptions in six NFL seasons.

This may be a sign that second-year player Alphonso Smith may not be completley ready to contribute. Smith was replaced by undrafted free agent Tony Carter late last season. Denver gave up its 2010 No. 1 pick (No. 14 overall) to Seattle to draft Smith at No. 37 last year.

• Kansas City re-signed backup running back Jackie Battle. He played in 17 games the past three seasons for the Chiefs.

• Former Denver starting guard Ben Hamilton is visiting with the Seahawks. Denver does not want to bring him back.

• Here is a chance to keep up with all the free- agency movement on ESPN.com.

• Oakland brought back left tackle Khalif Barnes. He was hurt last year, his first in Oakland. If he stays healthy, he could vie for playing time.

• Oakland hired Kevin Ross to work with the secondary. He replaces Clancy Pendergast, who quit Oakland two weeks after he took over as the defensive coordinator at Cal.

• New England re-signed guard Stephen Neal. He was a considered a possibility in Denver and Kansas City.

• Detroit cut massive defensive tackle Grady Jackson. Jackson, 37, could interest both Oakland and San Diego. He could fit both the 4-3 and 3-4 defenses.
