Niners agree to trade Hill to Lions

<p>The 49ers gave quarterback Shaun Hill permission to seek a trade last week. On Sunday, the team agreed to trade Hill to the Detroit Lions for a seventh-round pick in the 2011 draft, according to a league source.</p><p>Hill, 30, is set to become the Lions' backup to Matthew Stafford, the No. 1 overall pick in the 2009 draft. Scott Linehan is the Lions' offensive coordinator. Linehan was Minnesota's offensive coordinator for three of Hill's four seasons with the Vikings.</p><p>Hill lost his spot on the 49ers' depth chart when the club agreed to terms with quarterback David Carr on a two-year, $6.25 million salary.</p><p>The 49ers have yet to announce the transactions because Carr went on a vacation to Mexico and had not signed the contract. He is expected to deliver the document when he reports to Santa Clara for the 49ers' offseason program, which begins Monday.</p><p>The completion of the trade is contingent on Carr's contract, as well as Hill passing a Lions team physical. As of Sunday evening, Hill had not been informed about the trade by anyone with the 49ers or the Lions, said a source close to him.</p><p>Hill did not attempt a regular-season pass in his first five NFL seasons. After injuries to Alex Smith and Trent Dilfer, he won both of his starts in 2007 on a team that finished with a 5-11 record.</p><p>His steady play at the end of the 2008 season was one of the big reasons the 49ers won five of their final seven games, enabling Mike Singletary — who took over at midseason for fired Mike Nolan — to be elevated to the permanent coaching job.</p><p>Hill started the first six games last season before Smith replaced him at halftime against the Houston Texans on Oct. 25, trailing 21-0. Hill did not play for the remainder of the season. The 49ers were 10-6 in his 16 career starts.</p>
