Washington DC, July 23 -- Law & Order is undergoing a major change as actor Reid Scott, who has played Senior Detective Vincent Riley for the past three seasons, is set to exit the show. He will be replaced by actor James Badge Dale, reported Deadline.

For Scott, who is believed to have one more year on his contract, the departure is said to be his decision, related to the strain caused by the cross-country commute and being away from his family for nine months of the year while filming Law & Order in New York.

According to Deadline, Detective Riley will get a proper ending as Scott is back on the set, filming a few episodes to wrap the character's arc before Dale is introduced. The exact timing of the transition is unclear.
