The Boston Herald and WBZ-TV in Boston, citing sources, reported Tuesday that Amendola's timeline for a return to action is now a few weeks. Fox Sports had previously reported that Amendola has torn adductor muscles in his hip, and that there was conflicting medical opinions on whether Amendola had a sports hernia.
Had Amendola undergone surgery for a sports hernia, he reportedly would have been sidelined for about a month.
Amendola was present at the start of the Patriots' full-pads practice Wednesday morning.
Reporters saw Amendola jog with his teammates, go through agility drills and then catch a few lightly thrown passes. He didn't take part in every drill and wasn't running at full speed.
Amendola initially injured his groin in a preseason game against the Tampa Bay Buccaneers on Aug. 16. He missed the Patriots' final two preseason games before aggravating the injury late in the second quarter of the Patriots' regular-season opener last Sunday.
Amendola played through the injury in the second half of the opener, making two clutch receptions on New England's game-winning drive and finishing with a team-high 10 catches for 104 yards against the Buffalo Bills. He missed Thursday's 13-10 win over the New York Jets.
