Shaun Hill has been named the San Francisco 49ers' new starting quarterback.
He replaces turnover-prone J.T. O'Sullivan in the first big personnel move of coach Mike Singletary's tenure.
Hill won the first two starts of his career late last season after spending his first five NFL campaigns as a seldom-used backup or third-stringer.
He lost a three-way competition with O'Sullivan and Alex Smith during training camp this summer, but O'Sullivan has struggled with 11 interceptions and 11 fumbles in seven and a-half games.
Hill replaced O'Sullivan for the final play in the first half of the Niners' 34-13 loss to Seattle yesterday.
O'Sullivan fumbled on the 49ers' first two possessions and later threw an interception that was returned 75 yards for a score.
Hill played the entire second half, going 15-of-23 for 173 yards and a touchdown.
