Eric Baylor, 23, faces a charge of aggravated battery domestic violence after an incident in which he allegedly stabbed Williams in the thigh Sunday at the receiver's Tampa home.
Williams was treated for a minor laceration at St. Joseph's Hospital and released.
Police had issued a warrant for Baylor's arrest after there were conflicting accounts of what took place.
Williams reportedly told police he and Baylor were wrestling and he was accidentally stabbed during the horseplay. But according to police, multiple witnesses said Baylor and Williams had an argument that led to the stabbing.
The Buccaneers released a statement Sunday, saying they were aware of the situation and that the team's primary concern was Williams' well-being.
General manager Jason Licht reaffirmed those sentiments Monday but also said that the team had not heard from Williams.
"Obviously, our primary focus is making sure that he's OK," Licht said. "I know he's been treated and released. I just want to make sure that he's OK, and that's our main concern."
Sunday's incident is the latest off-field issue for Williams, who signed a six-year, $40.25 million deal with Tampa Bay last July. Williams faces misdemeanor charges of criminal mischief and trespassing, and he has paid more than $43,000 in damages for destructive house parties.
