San Francisco 49ers linebacker Aldon Smith pleaded no contest Wednesday to three felony weapons charges and two misdemeanor counts of driving under the influence. The 24-year-old Smith entered his pleas in a Santa Clara County Superior Courtroom in San Jose. He faces a sentence ranging from spending no time in custody to a maximum of four years and four months behind bars at a judge's discretion, prosecutors said. Smith is scheduled to be sentenced on July 25 -- two days after the 49ers are to open training camp in Santa Clara.
