The Oakland Raiders turned their attention to defense on day two of free agency.

One day after spending big to bring in two players to bolster the offensive line, the Raiders were preparing to host a number of free-agent defenders.

Former Pittsburgh linebacker LaMarr Woodley tweeted that he was headed for a visit to Oakland and a person with knowledge of former Dallas defensive tackle Jason Hatcher's plans said he is also planning to visit after meeting with Seattle. The person spoke on condition of anonymity because the team does not announce free agent visits.
