New England Patriots tight end Rob Gronkowski has been cleared from the concussion protocol and will play in Sunday’s Super Bowl against the Philadelphia Eagles.

Gronkowski participated fully in practice on Thursday. Defensive lineman Deatrich Wise also practiced after being cleared from the concussion protocol. Malcolm Butler (illness) and Brandon King (knee) also participated in the workout.

Gronk said he is “ready to roll” and has no limitations. He had been sidelined since taking a helmet-to-helmet hit from Jacksonville’s Barry Church in the first half of New England’s AFC championship game win.

The All-Pro tight end missed last year’s Super Bowl win over Atlanta after undergoing back surgery.

Gronkowski said he believes that the team doctors were just using the bye week to be as cautious with the injury as possible.

“We knew the whole time I was gonna be good to go,” he said. “I was progressing really good throughout the week. We just knew I’d be ready and we’ve been practicing like we always do.”

Gronkowski led the team in receiving during the regular season with 69 catches for 1,084 yards and eight touchdowns.

His return gives quarterback Tom Brady another key option against an Eagles defense that finished the regular season ranked fourth in the NFL in defense.

Labor negotiations: DeMaurice Smith dismissed with one word a question about his union’s labor deal with the NFL being extended.

Then he attacked.

The executive director of the NFL Players Association quickly said “no” Thursday when asked about the current 10-year collective bargaining agreement getting extended beyond the 2020 season.

Then Smith, re-elected last year, went on the offensive about the next CBA.

“We prepare for war,” he said. “If we are able to get a collective bargaining agreement done, great. All of these men went through a unilateral war declared on players in 2010-11.”

NFLPA President Eric Winston stressed there are many portions of the current contract they believe need changing, from health care issues to the union’s role in overall league decisions to, naturally, revenue splits.

“We want 99 percent of the revenues,” Winston joked before adding the structure of rookies’ contracts, health care and technical field issues as key elements for negotiations.

Ryan Wendell said workplace player safety would be an important topic, along with “more unfettered union access to the players.”

Shazier released from hospital: Injured Pittsburgh Steelers linebacker Ryan Shazier is going home.

Shazier was released from the hospital on Thursday, nearly two months after suffering a spinal injury in a victory over Cincinnati. The Pro Bowl player underwent spine stabilization on Dec. 6 and while he was able to travel a bit, including visiting team practices and making appearances at Heinz Field for games, he returned to the hospital each evening.

The University of Pittsburgh Medical Center says Shazier will transition to an outpatient therapy program.
