New England Patriots tight end Rob Gronkowski practiced for a second straight day Monday, but coach Bill Belichick did not say when he would be ready to play.
Gronkowski had multiple forearm surgeries and a back operation during the offseason. He practiced in full pads Sunday for the first time since the surgeries. Monday's practice session was similar to a walk-through in helmets and shells.
But that does not mean Gronkowski is healthy enough for game action.
"There is no straight-line formula for that," Belichick said. "We take it day to day. I don't know any other way to do it. We don't know how he's going to be feeling in two days. Or any other player. It's not about him, it's about any player that's coming back from injury. That's how we do it. Nobody has a crystal ball."
But Belichick added that Gronkowski's presence in practice is a positive sign.
"This is his first opportunity to be in pads," he said. "So, yeah, he's definitely moving forward."
When asked if Gronkowski had a chance to play this Sunday's season opener against the Buffalo Bills, Belichick said he is "day to day."
Gronkowski was put on the 53-man roster Saturday rather than placed on the physically unable to perform list, which would have kept him out the first six weeks of the regular season.
The Patriots have a quick turnaround after the opener. They host the New York Jets four days later on Sept. 12.
