Lee will be sidelined for four weeks while recovering from an oblique injury, Roch Kubatko of MASN Sports reports.
Lee will miss the rest of spring training after facing just one batter during his outing against the Rays on Tuesday. That was just his second appearance in the Grapefruit League and he seemed to be holding his right side while exiting the contest with a trainer. Once the regular season rolls around, Lee should be back at the Triple-A level in Norfolk, where he posted a 5.11 ERA and 1.71 WHIP over 27 appearances last year.
