Villanueva played 100 percent of snaps on offense during Monday's 27-14 win over the Dolphins.
Villanueva's reliable play has been a bright spot for Pittsburgh's otherwise shaky offense this season. The starting left tackle is facing a tough upcoming slate of matchups, however, with the Colts, Rams and Browns -- three teams that boast formidable defensive fronts -- on deck.
Villanueva played every snap on offense during Sunday's 28-26 loss to the Seahawks.
Villanueva also played four snaps on special teams. The veteran lineman is being relied on as Pittsburgh's every-down starter at left tackle, and he'll work to protect second-year quarterback Mason Rudolph on Sunday versus the 49ers.
Villanueva (illness) was absent Wednesday from the Steelers' injury report.
Villanueva missed some snaps in Sunday's victory over the Vikings while he was slowed down by heat-related issues. Now fully rested and hydrated, the veteran left tackle should resume his role protecting quarterback Ben Roethlisberger's blind side in the Steelers' Week 3 tilt with the Bears.
Villanueva is questionable to return to Sunday's game against the Vikings due to heat-related issues, Ray Fittipaldo of the Pittsburgh Post-Gazette reports.
If Villanueva can't return, Jerald Hawkins will be relied upon to protect Ben Roethlisberger's blind side. This injury likely won't amount to anything long term, but keeping an eye on his recovery would be wise considering his value to Pittsburgh's offensive front.
Villanueva participated in Thursday's practice, Ray Fittipaldo of the Pittsburgh Post-Gazette reports.
Villanueva suffered from a concussion a little over a week ago, but it appears as though he has cleared protocol and should be good to go for the remainder of the preseason so long as he stays healthy.
Villanueva was checked for a possible concussion after Tuesday's practice, Joe Rutter of the Pittsburgh Tribune-Review reports.
This could hinder Villanueva from playing Friday against the Giants. While he's out, Matt Feiler and Jake Rodgers will rotate into first-team snaps.
Villanueva signed a four-year contract with the Steelers on Thursday, Jeremy Fowler of ESPN reports. His deal is reportedly worth $24 million.
Villanueva had refused to sign his exclusive rights tender and was facing a possible holdout before agreeing to terms with Pittsburgh on Thursday. As the team's starting left tackle, Villanueva is a key cog in the Steelers offensive line that allowed the second-fewest sacks in the NFL last season.
The Eagles trimmed their roster to 76 players Saturday, as they announced the waiving of 14 players.
Among those waived are: wide receivers Kadron Boone and B.J. Cunningham; tight ends Emil Igwenagu and Blake Annen; offensive lineman Michael Bamiro, Karim Barton and Donald Hawkins; linebacker Jake Knott; defensive backs Daytawion Lowe and Davon Morgan; defensive linemen Joe Kruger, Frances Mays and Alejandro Villanueva; and kicker Carey Spear.
The team still has to make one more cut before Tuesday.
