New England Patriots tight end Rob Gronkowski did not make the trip to Buffalo for Sunday's season opener against the Bills, according to NFL.com.
Gronkowski, coming back from multiple forearm and back surgeries, was listed as doubtful on the team's injury list Friday.
Gronkowski missed the preseason but returned to practice this week. Coach Bill Belichick said Gronkowski is considered day-to-day, although he reportedly has been expected to miss the Patriots' first two games. New England has a quick turnaround as it hosts the New York Jets on Thursday.
Undrafted rookie Zach Sudfeld is expected to be the Patriots' primary receiving threat among tight ends in Gronkowski's absence.
Also, the Patriots re-signed running back/kick returner Leon Washington and promoted offensive lineman Josh Kline from the practice squad. They released defensive linemen Jermaine Cunningham and Justin Francis off injured reserve.
Washington had 22 carries for 83 yards with one touchdown and handled kickoff and punt return duties for the Seattle Seahawks last year. He spent 2006-09 with the Jets before heading to Seattle in 2010.
The Patriots cut Washington during the final round of roster cuts last week. He reportedly drew interest from the New York Jets, among other teams. He is expected to play against the Bills.
---The New York Jets are releasing quarterback Brady Quinn on Saturday and then plan to re-sign him Monday, according to ESPNNewYork.com.
The Jets did not plan to activate Quinn for Sunday's season opener against the Tampa Bay Buccaneers and 4 p.m. ET Saturday is the deadline when veterans' salaries become guaranteed.
With Mark Sanchez out with a shoulder injury, the Jets signed Quinn to a one-year, $715,000 contract last Monday. The Jets want to keep Quinn around since their only healthy quarterbacks are rookie Geno Smith and Matt Simms. Neither has played in an NFL game.
Coach Rex Ryan said Friday he is leaning toward starting Smith and using Simms as the No. 2. Ryan does not like to activate three quarterbacks for a game, saying, "If you're (planning) on playing your third quarterback, you're probably not going to win. That's generally the reason. ... That's why, unless you have an injury going in, normally you don't dress three."
If the Jets are able to re-sign Quinn on Monday, they will have four quarterbacks on their roster, which is rare.
After getting released, Quinn will still make $45,000 this week.
The Jets might use the open roster spot to sign wide receiver Michael Campbell from the practice squad. Starter Santonio Holmes is questionable as he is recovering from foot surgery.
---Cincinnati Bengals offensive tackle Andrew Whitworth is out for Sunday's game against the Chicago Bears.
Whitworth, a Pro Bowler, was previously listed as doubtful as he is coming off knee surgery. He did not practice during the week.
He will miss his first start in more than four seasons, ending a consecutive streak of 67 starts.
Defensive tackle Domata Peko will take over as the team leader in consecutive starts with 52 and defensive end Michael Johnson will play in his team-high 68th straight game.
Anthony Collins, a sixth-year player out of Kansas, will start in place of Whitworth. He also filled in for Whitworth in the preseason. He played five games last season. It is Collins' first start since 2011.
---Houston Texans safety Ed Reed will not start Monday night's season opener against the San Diego Chargers but could play, coach Gary Kubiak said Saturday.
Reed is considered a game-time decision as he is coming off hip surgery.
Reed was limited in practice during the week. He was on the physically unable to perform list during training camp and the preseason. He had surgery in April. He believes he sustained the torn labrum during the AFC championship game against the New England Patriots in January.
The nine-time Pro Bowler had injections two weeks ago to help in his recovery.
Shiloh Keo will start in Reed's place.
---The Miami Dolphins finalized a four-year contract extension with linebacker Koa Misi Friday night, the team announced.
