Tabata didn’t hit the wall overly hard in comparison to other crashes we’ve seen (easy for me to say) and the symptoms aren’t severe, though any head injury is of concern which lead to Tabata being removed from the game.
Thanks to the awareness around head injuries, Major League Baseball implemented the new 7 day disabled list for concussions a few seasons back and it’s very likely Tabata will find himself placed on such given the nature of the injury.
If Tabata is to miss any time, Travis Snider would likely take over his roster spot.
Tabata, coming off a very solid 2013 season, has had a slow start to the 2014 season, currently hitting a paltry .240 with just one home run and one double through 13 games. At minimum, it’s likely he misses a few days.
