The Raiders agreed to terms with Rodger Saffold to be their left tackle Tuesday, with Jared Veldheer departing to join the Arizona Cardinals, according to numerous reports.

Other reports have defensive end Lamarr Houston heading to Chicago to sign with the Bears and running back Darren McFadden agreeing to return to the Raiders on a one-year contract.

The Raiders are also reportedly in the mix for Tampa Bay cornerback Darrelle Revis, who is expected to be traded or released Wednesday.

The new league year began Tuesday at 1 p.m. and the Raiders have yet to confirm any transactions.

Saffold, the first pick of the second round of the 2010 draft (No. 33 overall) by the St. Louis Rams, has played both tackles spots and filled in at right guard last season.

In four seasons with the Rams, Saffold, 25, missed 17 of 64 games, with a torn pectoral in 2011 and a knee injury in 2012. He has started 16 games only once, in his rookie season. He was replaced as left tackle when the Rams signed Jake Long in free agency.

Veldheer, a third-round pick in the same draft as Saffold, was identified by general manager Reggie McKenzie and coach Dennis Allen as a player the Raiders wanted back. However, the club did not apply the franchise tag or sign Veldheer to a long-term deal before the free agency deadline.

"That you #raidernation for four great years," Veldheer said in a tweet with a Cardinals avatar. "You guys are awesome. I was blessed that Mr. Davis brought me into your community."

McFadden's return, reported by CSN Bay Area, comes as a surprise given his production last season (379 yards, 3.3 yards per carry) and injury history. McKenzie said following the season he expected McFadden's agent to test the open market, which he apparently did during the three-day open negotiation period.

Revis is due $16 million in salary in 2014 and it remains to be seen whether he would reduce that figure. A trade would also cost draft picks, something McKenzie has said in the past he would be reluctant to do.
