Snell exited Sunday's matchup with the Yankees early due to a tight left groin, Bob Nightengale of USA Today reports.
Snell was ultimately tagged with three runs over 4.2 innings in the outing Sunday, while his seven strikeouts matched a season high. It's unclear whether the left-hander will be forced to miss any additional action with the groin injury. His next projected start is tentatively set to come Saturday on the road against the Rangers.
