Patriots owner Robert Kraft remained hopeful yesterday the worst-case scenario would not play out for star tight end Rob Gronkowski, who is in a holding pattern with respect to a decision regarding a potential fourth surgery on his fractured left forearm.

Kraft yesterday sought an update on Gronkowski, who has been taking part in the team’s offseason program, and received what he perceived as positive news.

“Everything I’ve heard is good,” said Kraft, who was at the Putnam East Club yesterday, helping judge the fifth annual Science of Sports science fair along with Raytheon CEO Bill Swanson and Pats offensive lineman Nate Solder. “I asked about it this morning and everything is good. He’s working hard.”

As reported in the Herald last month, Gronkowski finished a six-week course of antibiotics to try and clear up an infection that has lingered since the second surgery. Doctors wanted to give it a little more time to see if the infection would disappear on its own before making a decision on whether it would be necessary to perform another surgery.
