49ers give Oregon's Blount a chance

49ers coach Mike Singletary famously promised his team would be so physical, it would hit people in the mouth.

BlountBlountFiguratively, of course.

LeGarrette Blount, the Oregon player who notoriously punched an opponent after a game, will have to control his temper more effectively if he hopes to stick with the 49ers.

San Francisco reached agreement with Blount as an undrafted free agent Saturday. ESPN's John Clayton called a bit ago with the news.

Singletary has effectively dealt with temperamental players, notably tight end Vernon Davis, who emerged last season as a first-team Pro Bowl performer after Singletary sent him to the locker room during a 2008 game against the Seahawks. Davis had drawn a personal foul for hitting the helmet of Seahawks safety Brian Russell.

The 49ers did not use an early draft choice for a running back.
