Roberts has been sidelined since April 9, when he strained an abdominal muscle sliding into second base against the Toronto Blue Jays. He's also been dealing with a herniated disk in his back, an injury that limited his participation in spring training.
The two-time All-Star has been playing for Double-A Bowie in a rehabilitation assignment this week. On Thursday, Roberts declared himself fit to return to the Orioles.
Speaking in the Baltimore clubhouse, Roberts said: "There's nothing I don't think I can do."
Interim manager Juan Samuel says the team will wait for the medical staff to clear Roberts before deciding whether to activate him from the DL.
