While the San Francisco 49ers have yet to publicly say they will trigger a 2015 option for linebacker Aldon Smith, they have long been expected to do so.Smith, a first-round pick in 2011, is covered under the collective bargaining agreement the league reached with the players union that summer. First-round picks have four year contracts, with a fifth year option. Smith's rookie contract runs out after this season. The deadline is May 3. Exercising the option is considered procedural.
