Colby Lewis‘ rehab from surgery to repair a torn flexor tendon has hit a momentary snag.
T.R. Sullivan of MLB.com reports that Lewis was unable to throw his scheduled bullpen session today due to right triceps soreness and could be scratched from his next rehab start on Tuesday.
Lewis, who had flexor tendon surgery last July, allowed four runs on three hits and two walks over two innings during his first start with Triple-A Round Rock on Thursday. The Rangers were aiming for him to make around four rehab starts before joining the rotation in late May or early June, so his timeline could be pushed back if the triceps issue lingers.
Lewis, 33, posted a 3.93 ERA over 80 starts with the Rangers from 2010-2012. He re-signed with the club last September on a one-year, $2 million deal and could make an additional $4 million with incentives.
