Skuta was arrested June 19 and charged with misdemeanor first-degree battery for an incident in Orlando, Florida. He had been accused of pushing a woman's face into a glass window.
"From the investigation which has been made, it is the opinion of the writer that this case is not suitable for prosecution," Assistant State Attorney Natalie Lord wrote.
In a statement, Skuta's lawyers Mark NeJame and Trey Flynn said Skuta was given "no special consideration" and that they were happy that the linebacker could now focus on the upcoming season.
Skuta had 40 tackles and 1.5 sacks in 2015 with the Jaguars.
