Quarterback Kyle Boller, a ’03 first-round pick of the Ravens, flamed out in Baltimore but apparently has found a home in Oakland.

The Raiders re-signed Boller quietly last week to a one-year, $1.25 million contract to back up starter Jason Campbell. The Raiders made the move before the end of the league year on Thursday but never announced the deal.

New coach Hue Jackson, the team’s former offensive coordinator who also coached Boller in Baltimore, chose to retain Boller, who turns 30 in June, over former starter Bruce Gradkowski and journeyman Charlie Frye. The team will allow Gradkowski and Frye to become free agents.

Boller appeared in five games last year, completing 2-of-4 passes. Boller, in seven NFL seasons, has completed 56.7 percent of his passes with 48 touchdowns, 51 interceptions for a 70.4 passer rating.

The Raiders also re-resigned free safety Hiram Eugene and guard Daniel Loper, according to the Oakland Tribune. Eugene, 30, signed a four-year, $10.25 million contract, and he is seen as the likely successor to pending free agent Michael Huff. Loper, 29, could be the successor to pending free agent Robert Gallery. Loper signed a two-year, $3.9 million deal.

The Oakland Raiders quietly re-signed four players last week before the expiration of the NFL’s collective bargaining agreement, continuing their active offseason, the Oakland Tribune reported Tuesday.

Quarterback Kyle Boller, safety Hiram Eugene, guard Daniel Loper and Michael Bennett each inked deals to remain Raiders, who also gave a second-round tender to reserve linebacker Ricky Brown, according to the Tribune.

Boller, who saw limited duty in five games, received a one-year $1.25 million contract. Fellow quarterbacks Bruce Gradkowski and Charlie Frye are unsigned.

Eugene, who appeared in 14 games, signed a four-year, $10.25 million contract that might signal the end of starting free-agent safety Michael Huff’s Raiders tenure, the Tribune reported.

Loper, who replaced Robert Gallery at left guard when Gallery was injured for four games, received a two-year, $3.9 million pact. The Raiders have said Gallery will not be re-signed.

Bennett received a one-year, $865,000 deal.

The Raiders have been among the NFL’s most aggressive teams this offseason, re-signing Pro Bowl defensive lineman Richard Seymour and cornerback Stanford Routt to contracts exceeding $30 million, placing the franchise tag on linebacker Kamerion Wimbley, and resigning defensive lineman John Henderson and special teams standout Rock Cartwright.

In addition, the Raiders previously tendered contracts to tight end Zach Miller and running back Michael Bush.

The Raiders also voided the contract of Pro Bowl cornerback Nnamdi Asomugha.
