Bruce Miller has been charged with seven felonies -- including assault with a deadly weapon that allegedly was a cane -- and one misdemeanor in connection with an incident involving a 70-year-old man and his son that ultimately led to the tight end's release by the San Francisco 49ers earlier this week.

Miller will be arraigned Friday, according to the San Francisco District Attorney's office.

Police there said they were called to the hotel at about 2:45 a.m. PT, after Miller tried to enter a room occupied by an elderly couple. The couple's 29-year-old son, staying in the next room, then told Miller he was at the wrong room.

Miller, who police say was intoxicated at the time, attacked the son and his father, who came to his son's defense, police said. The father was punched by Miller and both men were taken to the hospital for their injuries, according to police.

Miller was booked in county jail at 11:25 PT on Monday morning. Hours later, the 49ers released him.

The SFDA said Thursday that Miller faces seven felony charges, including one count of assault with a deadly weapon that allegedly was a cane. The other felony charges were: one count of assault with force to cause great bodily harm; one count of inflicting injury on an elder or dependent adult likely to cause great bodily injury; one count of battery with serious bodily injury; one count of assault with force likely to cause great bodily injury; and two counts of criminal threats.

Miller also faces a misdemeanor battery charge.

The 29-year-old Miller signed with the team in 2011 as a fullback after playing defensive end in college. He was a key part of San Francisco's teams that went to three straight NFC title games and one Super Bowl in his first three years. In 77 games over five seasons, he has 62 yards rushing on 28 carries, adding 76 catches for 734 yards.

A call to Miller's attorney, Joshua Bentley, was not immediately returned.

Miller's agent, Jack Reale, said there was more to the case than meets the eye but declined additional comment.
