Betts was scratched from the lineup for Friday's game against Cleveland due to a right rib contusion, Juan Toribio of MLB.com reports.
It's unclear when Betts suffered the injury, though it could potentially be related to his 2-for-30 slump over his last seven games. As long as his injury remains nothing worse than a bruise, it's likely he won't need a trip to the injured list, though it's still possible he sits for at least a couple more games.
