SIOUX FALLS, S.D. - Prosecutors expect to ask a grand jury to consider more serious charges in the death of the 2-year-old son of Vikings running back Adrian Peterson.
Tom Wollman, Lincoln County state's attorney, said Tuesday he'll review the recently completed autopsy findings and other reports before looking at any new charges against Joseph Robert Patterson, 27.
"We'll seek a grand jury review in the near future," Wollman said.
Sioux Falls police identified the boy as Tyrese Robert Ruffin, who died Friday from severe head injuries. Patterson, the boyfriend of Tyrese's mother, was charged last week with aggravated assault and aggravated battery and is being held on $750,000 cash bond.
Peterson, who has declined to discuss the relationship he had with the boy, rushed to the Sioux Falls hospital to see the child Thursday, missing practice.

Bucs release hurt CB
The Bucs have another opening on their 53-man roster, as rookie cornerback Rashaan Melvin was placed on injured reserve after he was limited by a hamstring injury.

Hernandez case: The girlfriend of former Patriots tight end Aaron Hernandez pleaded not guilty of perjury for allegedly lying to a Massachusetts grand jury, including about disposing of evidence in the murder case against him. Shayanna Jenkins was released on personal recognizance in Fall River Superior Court. Hernandez, 23, a former Florida star, has pleaded not guilty to the June murder of Odin Lloyd, who was dating Jenkins' sister. Hernandez is held without bail.
Taylor trial: Fifty potential jurors were questioned as the trial for the man accused of killing former Redskins and University of Miami star Sean Taylor began. Eric Rivera Jr., 23, faces a first-degree murder charge in the 2007 slaying of Taylor.
Vick limited: Eagles quarterback Michael Vick practiced on a limited basis, but there was no word on his status for Sunday's game against Dallas. Vick suffered a hamstring injury Oct.6 against the Giants and missed Sunday's game at Tampa Bay.
New Steeler out: Levi Brown's tenure at left tackle for the Steelers ended before it began. Pittsburgh placed Brown on injured reserve two days after he tore a triceps while warming up for Sunday's game against the Jets. He had been acquired from the Cardinals last week. Tight end David Johnson (wrist) is also out for the season.
BILLS: Starting left guard Colin Brown was released in favor of Doug Legursky.
JETS: They signed former Browns kick returner Josh Cribbs. The three-time Pro Bowl selection was cut by Oakland in the preseason after offseason knee surgery. Cribbs is tied with New England's Leon Washington for the most kickoff-return touchdowns in NFL history with eight, and has returned three punts for scores.
PACKERS: Wide receiver Randall Cobb is out for at least six weeks with a knee injury. The team placed Cobb on injured reserve/designated for return. Cobb was hurt in Sunday's win over the Ravens after a low hit from safety and former Florida star Matt Elam.
REDSKINS: Safety Trenton Robinson, linebacker Josh Hull and long snapper Kyle Nelson signed, and safety Jordan Pugh was cut.
