Hayes underwent back surgery according to head coach Adam Gase, Adam Beasley of The Miami Herald reports.

EDGE Analysis

The surgery stems from a lingering back issue that Hayes has been dealing with for some time but it's unknown how long the recovery process will be. The defensive lineman recently signed a one-year extension to remain in Miami after finishing with one sack in 10 games last season.

Hayes signed a one-year contract extension with the Dolphins on Wednesday, Mike Garafolo of the NFL Network reports.

EDGE Analysis

Hayes is entering his 11th year in the league, with the 2017 season being his first in Miami. The 2008 fourth-rounder only racked up 19 tackles and one sack in 12 games, however, before landing on injured reserve with a hamstring injury. Fortunately, Joe Schad of the Palm Beach Post reports that Hayes has since recovered and should be "ready to roll" for the offseason.

Hayes (hamstring) was placed on injured reserve Tuesday.

EDGE Analysis

Hayes is expected to undergo surgery on his hamstring so his season comes to an end after 10 games, in which he recorded 19 tackles (14 solo) and one sack. Look for Charles Harris and Terrence Fede to potentially see increased defensive roles with Hayes sidelined.

Coach Adam Gase said Monday that Hayes is expected to have hamstring surgery and be ruled out for the rest of the season, Ian Rapoport of NFL Network reports.

EDGE Analysis

Hayes was on this week's injury report with a back injury, but it'll be a hamstring injury that ends the defensive end's season. Hayes was used as a depth option on the defensive line, and his absence should result in Charles Harris and Terrence Fede potentially seeing bigger roles as reserve defensive ends.

The Dolphins have ruled Hayes out for Sunday's matchup against the Patriots, Armando Salguero of the Miami Herald reports.

EDGE Analysis

Hayes' absence for the Week 12 game is not surprising, as he was unable to participate at practice throughout the week. As a result, look for Charles Harris and Terrence Fede to see bigger roles providing depth at defensive end.

Hayes (knee) is active for Sunday's game against the Buccaneers.

EDGE Analysis

Although Hayes is a backup on the depth chart, he's still logged 30 or more snaps in each of his last three matchups. However, he hasn't been able to post a high tackle count in his limited snaps, which keeps him off fantasy owners' radars.

Hayes (knee) is listed as questionable for Sunday's game against the Buccaneers, Adam H. Beasley of the Miami Herald reports.

EDGE Analysis

Hayes put in full practices Thursday and Friday, so his knee injury doesn't look to be anything serious. Even so, Hayes is behind Cameron Wake and Adrian Branch in the pecking order at defensive end, so he'll be little more than a rotational player if he suits up Sunday.

Hayes (knee) was a full participant in practice Thursday, Adam Beasley of the Miami Herald reports.

EDGE Analysis

Hayes did not practice Wednesday due to a knee injury but appears to have made some progress given his return to the field Thursday. Barring any major setbacks, the defensive end should be ready to go for Sunday's game against the Buccaneers.

Hayes (knee) isn't practicing Wednesday, Armando Salguero of the Miami Herald reports.

EDGE Analysis

Hayes appears to be dealing with a different injury than the hamstring issue that hindered him at the start of the month. His availability in practice Thursday and Friday will be more indicative of his status for Sunday's game against the Bucs.

Hayes (hamstring) is active for Week 9's game against the Raiders.

EDGE Analysis

Hayes' presence will be a huge boost to a Dolphins run defense, which has yielded 95.4 yards per game so far to opposing rushers.
