Wilfork (groin) is day-to-day, according to head coach Bill O'Brien.

EDGE Analysis

The veteran defensive tackle has been sidelined at practice this week after suffering a groin injury in Week 8 against the Lions. Wilfork had some extra time to heal during the Texans' bye last week, but the injury could still prohibit him from taking the field this Sunday. If that is the case, look for D.J. Reader to receive the spot start.

Wilfork did not participate in practice Monday due to a groin injury, Aaron Wilson of the Houston Chronicle reports.

EDGE Analysis

Wilfork sustained his injury during the Texans' pre-bye game against the Lions in Week 8 and did not return. If he's unavailable to play Week 10 against the Jaguars, rookie D.J. Reader could make his first career start in his place.

Wilfork suffered a groin injury in Sunday's contest against the Lions and is questionable to return.

EDGE Analysis

Wilfork is the anchor along the Texans' defensive line, so a prolonged absence would likely affect Houston's run defense negatively. D.J. Reader stands to see increased snaps as long as Wilfork remains out.

Wilfork has signed with the Texans, the Boston Herald reports. The 33-year-old Wilfork isn't a major IDP factor these days, having recorded 47 tackles for the Patriots in 16 games last season, but he remains an asset as a run defender and should step right into the starting nose tackle position for Houston.

Wilfork will become an unrestricted free agent when eligible next week, ESPN's Adam Schefter reports. The Patriots declined to pick up the team option on Wilfork's contract, so he will be free to explore other opportunities at the onset of free agency. The 33-year-old defensive tackle tallied 47 combined tackles in 2014, but didn't record a sack for the second straight year. The report, which was relayed by Schefter, came from Wilfork's personal Twitter account.

Wilfork said Thursday that he will play at least one more season, WEEI.com reports. Signed through 2016, Wilfork was very clear about the fact that he plans to continue playing. The Patriots could free up approximately $8 million in 2015 cap room by releasing Wilfork, but the two sides will almost certainly agree to a mini-extension or restructure.

Wilfork was on the field for 22-of-52 of the Patriots' defensive snaps in Friday's preseason game against the Panthers, ESPN.com reports. While Wilfork recorded just one tackle in the game, both ESPN and the Boston Herald suggest that Wilfork seems past his Achilles' woes at this stage. While the veteran DT is only an IDP factor in deeper formats, his return to the the Patriots' defensive front line should represent a big boost to the team's overall defense, in particular against the run.

Patriots NT Vince Wilfork (Achilles') is practicing without restriction. Wilfork will likely he held out of some 11-on-11s, but he's full steam ahead for Week 1. That being said, we'd expect him to see very limited action in the preseason. There's simply no reason for the Patriots to take the risk.

Patriots NT Vince Wilfork (Achilles') is on track to be ready for training camp. Wilfork is participating in individual drills at OTAs and has even progressed to some 11-on-11 work. He tore his Achilles' in September, but there haven't been any setbacks. Even if Wilfork misses time, his Week 1 status isn't in doubt.

Vince Wilfork (Achilles') is participating in individual drills at OTAs. Wilfork tore his Achilles' in late September. He's working on the side at Patriots OTAs, along with fellow DT Tommy Kelly (torn ACL). Wilfork is questionable for the start of training camp but should be ready in plenty of time for Week 1. He's entering hiss 11th season with New England.
