Brandon Morrow injury: Blue Jays starting pitcher having tests done on back

Blue Jays starter Brandon Morrow stayed back in Florida while the team moved on to Boston. Morrow remained to have tests done on his back.

The Blue Jays still have Morrow scheduled to start on Sunday, reports Barry Davis of Sportsnet. The right hander was originally slated to pitch Friday, but had his start pushed back two days due to spasms in his neck and back.

Blue Jays manager John Gibbons said on Thursday that Morrow had his back lock up during a side session. With the nature of spasms, it is possible the Blue Jays will not know until Sunday whether or not Morrow will be able to make his start. Depending on what tests show, there is a chance that the Blue Jays could be forced to place Morrow on the disabled list, but that does not appear to be a likelihood at this point.

The Blue Jays are already missing two-fifths of their starting rotation as Josh Johnson and J.A. Happ are both currently on the disabled list. The other two members of Toronto's starting staff--R.A. Dickey and Mark Buehrle--have not pitched particularly well this season. Dickey also is not playing at full strength right now as he has dealt with back and neck tightness during the season.

Morrow has been the best starting pitcher on Toronto's staff this season, posting a 4.69 ERA with a 7.59 K/9.
