FOXBOROUGH, Mass. -- New England Patriots receiver Danny Amendola underwent surgery on his left knee earlier this offseason, in addition to a procedure to remove bone spurs from his ankle, but his rehabilitation has been on a positive track and he's already moving well, sources told ESPN.
Amendola's situation was referred to as "minor" and "not a long-term" concern, according to sources.
The Boston Herald first reported the surgeries on Monday.
Amendola's rehabilitation, coupled with fellow receiver Julian Edelman's recent surgery on his left foot, means two of the Patriots' top three receivers aren't yet cleared for action.
Their status will be monitored closely as the team approaches the start of training camp in late July. In offseason camps, the team will give other receivers -- such as free-agent signings Chris Hogan (Bills) and Nate Washington (Texans) and rookies Malcolm Mitchell (fourth round) and Devin Lucien (seventh round) -- additional repetitions at the position.
Amendola restructured his contract to remain with the Patriots earlier this month, which made it the second straight year in which he adjusted his deal to stay with the team. Amendola's restructured contract is for a maximum value of $7.35 million over two years, with an additional $750,000 in incentives and roster bonuses, sources confirmed to ESPN.
Amendola was scheduled to earn $5 million in base salary and count $6.8 million on the salary cap, which made it unlikely that he would remain with the club unless the sides revisited the deal. He was scheduled to earn a base salary of $6 million in 2017.
Amendola injured his left knee at the end of a 41-yard catch in a Nov. 23 win over the Buffalo Bills and had to manage the knee carefully the rest of the season. He missed the following week's game at Denver, and in a Dec. 20 game against the Tennessee Titans, he left in the second quarter and didn't return.
"I just banged my knee on the ground. Somebody got on my back and hit my knee on the ground," he said at the time in explaining how the knee was injured.
Amendola has been working out at the team's offseason program since it began April 18. Last week, he described how the loss to the Denver Broncos in the AFC Championship Game has created an urgency of sorts among his teammates.
"It was a rough day, but at the same time, it's motivated us to have a good, strong offseason, get healthy and get our guys ready in here to get back to work," he said. "We've all been working really hard and are excited to get back out there. We have a lot of new faces in the building. It's great to see the young cats coming in, and then the old guys kind of pushing them and letting them know the Patriot Way."
