To clear room Monday, Indianapolis released running back Dion Lewi from the active roster and guard Josh Walker from the practice squad.
The 6-foot-4, 294-pound Quarles was waived by New England on Aug. 31. The undrafted rookie originally signed with the Giants in May. He could help fill the void left by defensive lineman Arthur Jones, who sustained a high right ankle sprain in Monday night's 30-27 loss to Philadelphia.
Arkin played in one game with Miami last season and was Dallas' fourth-round pick in 2011.
Indy (0-2) signed Lewis last week. Walker, an undrafted rookie, was signed by the Colts in May.
