The Charlottesville Daily Progress reports the items were taken from George Huguely's apartment during a search on Monday by Charlottesville police.
Huguely has been charged with first degree murder in the death of Yeardley Love, an ex-girlfriend.
The U.Va. senior's early Monday morning by her roommate and the roommate's boyfriend.
The Progress reports that police also recovered two laptop computers, a notebook and other items from Huguely's apartment.
Huguely is also a U.Va. senior and university lacrosse player.
The arrest of Huguely and death this week of Love, both 22, have struck the highly-ranked teams as they prepare for the NCAA tournament and shaken many on the picturesque campus where students are studying for finals. The teams will compete in the tournament, and the university's athletic director, Craig Littlepage, said Love's family supported that decision.
About 3,000 people grieved Love's loss at a candle light vigil in a packed U.Va. amphitheater Wednesday night.
Love's funeral was set for Saturday in her home state of Maryland. Huguely remained behind bars.
Love will be awarded a degree posthumously at graduation later this month, reports CBS News Correspondent Whit Johnson.
According to a search warrant affidavit, Huguely admitted he'd kicked in her bedroom door, shook her, and that her head repeatedly hit the wall.
His attorney, Francis Lawrence, called Love's death an accident.
In court documents filed Wednesday, Charlottesville police said they took the stained jersey, the letter to Love and other items from Huguely's apartment hours after Love's body was discovered, the Daily Progress says. The court records were later sealed.
Police are investigating any previous violent incidents between the couple.
Charlottesville Police Chief Tim Longo says they "have no documented police reports of any of these kinds of behaviors."
Two years ago, Huguely was charged with resisting arrest and public intoxication. Police used a Taser to take him into custody.
On Wednesday, Littlepage claimed to have no record of the misconduct, saying, "I never heard it. Absolutely never heard it."
