The Oakland Raiders signed trouble-prone former San Francisco 49ers outside linebacker Aldon Smith to a one-year deal. They cut Lavar Edwards to create a spot for Smith. Smith recorded 44 sacks in 50 regular-season games during his time with the 49ers "Aldon is an extremely talented young player," coach Jack Del Rio said in the statement. "We welcome him to the Raiders family and expect him to bring his best every day and be a great teammate." Smith was charged with three misdemeanors Friday: driving under the influence with a prior conviction and refusal to submit a chemical test, hit and run with property damage and vandalism with damage under $400. He is set to be arraigned Oct. 6. The maximum penalty is two years and six months in county jail if he is convicted of all three charges. Smith is expected to be suspended at some point this year. "We are confident that the Raiders provide an environment where Aldon can thrive through the support, structure and leadership within the building," general manager Reggie McKenzie said in the statement. "We are excited to have Aldon here in the Raiders family." Follow me on Twitter: @AaronWilson_NFL Aaron Wilson covers the Texans for The Houston Chronicle.
