Reynolds, 30, was charged in December over an alleged domestic violence incident.
However, the Tigers confirmed on Wednesday that charges against Reynolds had been dropped.
"This news comes as a great relief to Josh as well as our club," Tigers chief executive Justin Pascoe said in a statement.
"Josh has carried himself extremely well throughout what has no doubt been a very stressful time for him and his family, and we look forward to him continuing to play a key role for this club on and off the field in the years to come."
