The Rays placed Palacios on the 10-day injured list Friday with a right knee sprain, Ryan Bass of Bally Sports Sun reports.
Palacios suffered the injury in Wednesday's loss to the Marlins. The severity of the sprain hasn't been revealed, so it's not clear at this point how long the super utility player might be sidelined. Kameron Misner is absorbing Palacios' spot on the Rays' roster.
