FOXBOROUGH, Mass. -- New England Patriots tight end Rob Gronkowski returned to practice Friday for the first time since breaking his forearm Nov. 18 against the Indianapolis Colts and is listed as questionable for Sunday’s game against the San Francisco 49ers.

Gronkowski, who did not participate in Wednesday's walkthrough session or Thursday's practice in light shoulder pads, joined his teammates for Friday's in-stadium workout, but was limited. Reporters were in the locker room immediately after Friday's practice concluded, and when they entered, Gronkowski's chair at his locker was already folded up, suggesting that he had not completed practice with his teammates.

Even if Gronkowski suits up Sunday, which is considered a long shot, it is unlikely he would play a major role.

In total, a season-high 19 Patriots were listed as questionable for Sunday, including cornerback Aqib Talib (hip) and Alfonzo Dennard (hamstring), both of whom were injured last Sunday against the Houston Texans.

Offensive tackle Nate Solder was added to Friday's injury report as limited with an abdomen injury. He is also listed as questionable for Sunday night's game.
