Report: Gronk might need surgery

Rob Gronkowski‘s arm might be getting better, but the
Patriots tight end may now be dealing with a different issue.

According to
, Gronk recently underwent an MRI on his back to check a
disc issue he had from last season.

The source tells USA Today that this issue is with a different
disc than the one that required surgery in 2009 and that there has
been no decision whether back surgery will be required. Gronk will
also be reporting to spine specialist Robert Watkins after his
forearm surgery, according to the report. The record-setting tight
end has 38 touchdowns and 2,663 receiving yards in his first three
NFL seasons.
