49ers All-Pro linebacker Aldon Smith was named in a lawsuit filed Tuesday over an alleged shooting during a June 2012 party that Smith hosted at his San Jose, Calif., home.

Titans tight end Delanie Walker, who was Smith's teammate the past two seasons in San Francisco, was also named in the suit, which was obtained by NBC Bay Area.

Ronndale Esporias filed the suit and alleges that the players illegally fired weapons at the party. Esporias alleges that Smith and Walker brandished weapons that they knew were possessed illegally and fired multiple rounds.

Walker then allegedly fired shots from the balcony of the home in the air and toward some people at the party, according to the suit. A group of people near the street fired back at the house, according to Esporias, who claims he was hit during the crossfire.

Esporias says in the suit that he "sustained serious, catastrophic and permanent injuries" after being shot twice.

Smith was taken seventh overall by the 49ers in the 2011 draft. He was named first-team All-Pro last season after notching 19.5 sacks. Walker signed with the Titans in the offseason after recording 21 catches for 344 yards and three touchdowns last year in San Francisco.
