With Dennis Pitta and Ed Dickson sidelined, there will be increased playing time Matt Furstenburg, an undrafted rookie tight end from Maryland. "It's definitely been unfortunate for Dennis and Ed, but it's a great opportunity for other guys," Furstenburg said. "I want to prove myself out there and show what I can do not only here, but to other teams, too." ... Harbaugh reiterated that Dickson isn't expected to be out for an extended time as he recovers from a slightly torn hamstring. "Within a week or so, we'll re-evaluate that and see where we're at," Harbaugh said. "It's not going to be a long-term problem, but it's going to be something that's going to have to heal." Harbaugh said he doesn't think the injury will force Dickson to miss time in the regular season. ... Lacrosse legend Gary Gait, the Syracuse University women's lacrosse coach, attended Tuesday's practice and spoke with Harbaugh afterward.
