Texas Rangers reliever Luke Jackson will be returning to D/FW to have his lower back examined by Dr. Drew Dossett on Tuesday, per the beat guys on Twitter. Jackson has previously said that the lower back stiffness he is experiencing is something he usually deals with at the beginning of camp, but the Rangers have indicated they want to err on the side of caution with him.
Jackson, 24, made his major league debut last year, but is expected to start the season in the bullpen for AAA Round Rock. He made strides after converting to relief, but the righthander is behind a stacked group of relievers for a job in the major league pen, so for 2016, his role would seem to be to provide depth and insurance while continuing to develop in the minors.
The Rangers have already lost one of their righty relief depth options, Tanner Scheppers, for the first half of the season due to knee surgery. Of course, relief pitching is an area of depth for the team, and is one area they appear well situated to deal with a little bit of attrition. That said, hopefully Jackson's back issue is minor, and he'll be able to start the season on schedule.
