"Talk about freaky, he just slipped coming into the dugout," Rays manager Joe Maddon said. "... I think he grabbed the net and cut the inside of his hand. I didn't even want to look at it."
Navarro was taken to Columbia Presbyterian Hospital, where he was seen by Dr. William Levine, who needed 12 stitches to close Navarro's lacerations.
The Rays selected Mike DiFelice from Triple-A Durham to take Navarro's place. DiFelice is expected to join the team prior to Saturday afternoon's game against the Yankees.
Since reliever Juan Salas did not report to Spring Training due to visa problems, and has since been placed on the restricted list, the Rays used Salas' spot to place DiFelice on their 40-man roster.
Navarro was scheduled to bat in the top of the third inning with the bases loaded and one out before the accident. Shawn Riggans was sent in to pinch-hit and hit a pivotal three-run double to right-center field.
Navarro, who was 0-for-1 on Friday night, is hitting .333 in three games.
