Jerod Mayo LB NE 4 Days

Though Mayo (undisclosed injury) was in uniform, he did not play in Friday's preseason game against the Panthers, the Boston Globe reports.

Given that Mayo (who has been practicing of late) was viewed as a game-time decision for the contest and that he suited up, it doesn't appear that the linebacker's undisclosed injury is something that is likely to impact his regular season availability.

Mayo is dressed for Friday's preseason game, but will be a game-time decision, ESPN Boston's Mike Reiss reports.

It's unclear what is ailing Mayo, but he was limited this week in practice. Odds are it's not a very serious injury, as there's a chance he'll play Friday.

Mayo (undisclosed) returned to practice Monday, ESPN Boston reports.

Mayo missed three practices last week, as well as Friday's preseason game versus the Eagles, for an undisclosed reason. While an explanation for his absence still hasn't been provided, Mayo returned to action Monday and could be ready for Friday's exhibition contest against Carolina.

Mayo (unspecified issue) sat out practice again Thursday, ESPN.com reports.

It's unclear what's keeping Mayo off the field, but he's been out for three days thus far. In his absence, Dont'a Hightower has assumed some of Mayo's play-calling responsibilities, while Darius Fleming is among the players seeing added opportunities in practice.

Mayo (unspecified issue) missed his second straight day of practice Wednesday, ESPN.com reports.

Mayo was limited to six games last season due to a torn pectoral muscle, but he had been practicing prior to his current absence, so assuming no major setbacks, he appears on track to hold down the Patriots' starting middle linebacker job and thus re-emerge on the IDP radar thanks to his tackling prowess.

Patriots WLB Jerod Mayo (pectoral) is participating in Organized Team Activities.

Mayo is progressing well after missing the final 10 games of 2013. He's been cleared for team drills at OTAs and remains on track for training camp. With Dont'a Hightower moving into more of a pass rush role, Mayo and Jamie Collins are ticketed for the majority of snaps in the Patriots' nickel packages.

Patriots WLB Jerod Mayo (pectoral) isn't yet 100 percent.

Mayo went down in Week 6. "I don't know how it'll feel when we start going out there doing different things as far as a little bit of contact drills," Mayo said Tuesday. "Even though there's no pads, you can fall a certain way so I'm just gonna take it one day at a time and see how it goes." Mayo did say that he's getting stronger "every day." He's expected to be ready for training camp.

ESPN Boston expects Patriots LB Jerod Mayo (pectoral) to be ready for training camp.

Patriots placed WLB Jerod Mayo (pectoral) on injured reserve, ending his season.

Mayo needed surgery to repair the right pectoral muscle he tore against the Saints in Week 6. It's another massive blow to a defense that has already lost captain and Vince Wilfork (Achilles') for the season. Second-round rookie Jamie Collins will step in at weak-side linebacker, but he's going to struggle to replace a guy that has led the Patriots in tackles for five straight years, been to two Pro Bowls and calls the defensive plays. Mayo should be back in 2014 at a reasonable $3.25 million base salary.

ESPN Boston confirms that WLB Jeron Mayo (pectoral) is not expected to play again this season.

Mayo tore his pectoral during Sunday's win over the Saints and reportedly underwent surgery. The Patriots may be able to replace his talent with No. 52 overall pick Jamie Collins, but they won't be able to truly replace what he brings to a defense allowing just 16.2 points per game (fourth-best in the NFL). Mayo plays every down, calls the plays in the defensive huddle, has led the team in tackles in five straight years and has been to the Pro Bowl twice. The Patriots previously lost defensive captain Vince Wilfork (Achilles') for the season as well.
