Cashner and Wells are both on the disabled list and were scheduled to see team orthopedic specialist Dr. Stephen Gryzlo at Wrigley Field. An official update was expected Tuesday.
Neither pitcher has any pain or discomfort. Cashner, who has a strained right rotator cuff, and Wells, who has a strained right forearm, were placed on the disabled list April 7 and told they could not pick up a baseball for two weeks.
Wells was able to play catch Monday under the watch of pitching coach Mark Riggins.
