Two New York Yankees are preparing to have surgery this week, and in at least one of the cases it will be season ending.

Starter Michael Pineda is slated for Tommy John surgery to repair a partially torn Ulnar Collateral Ligament in his throwing arm. Based on 'the normal' course of rehab for such an injury, don't expect him to be ready for the start of 2018. Pineda got off to a 3-1 start in April and posted an 8-4 record with 4.39 ERA in 17 starts this season.

Meanwhile, Greg Bird has opted to have a bone growth removed from his foot area.

Manager Joe Girardi told MLB.com that it's expected to sideline Bird for about six-weeks so it's ''possible'' he could be back before the end of the year. The bone has limited Bird to just 19 games and 60 at-bats this season.
