Reyes left Monday's game with a bruised left elbow, the Fort Worth Star-Telegram's Jeff Wilson reports.
He has impressed the Rangers this spring, but the 27-year-old lefty was always facing an uphill battle to crack the roster out of spring training. If he has to miss a chunk of time with the elbow bruise, that should be enough to punch his ticket to Triple-A for the start of the season, where he would serve as organizational bullpen depth.
