Here's a look at stories from around the league on Friday, Sept. 22.
1. Sam Bradford is out again for the Vikings.
Vikings QB Sam Bradford will miss his second straight game with a knee injury, coach Mike Zimmer said Friday.
Case Keenum will make his second consecutive start in Sunday's game against Tampa Bay after losing last week to Pittsburgh. Bradford threw for 346 yards and three touchdowns in their Week One win over the Saints but couldn't go in Week Two.
2. Gronk says he's good to go.
Patriots tight end Rob Gronkowski (groin) told reporters Friday that he'll be ready for Sunday's game against the Texans.
Gronkowski logged 116 yards and a touchdown in Week Two but couldn't finish the game due to the injury.
Patriots receiver Danny Amendola (concussion) also said he'll play Sunday.
3. Corey Graham's ironman streak to end.
Eagles safety Corey Graham, a Buffalo native and former Bill, will have his consecutive games streak snapped at 159 Sunday. The team has ruled him out with a hamstring injury.
Graham's streak of consecutive games played was the longest of any safety in the NFL and second among all defensive players, behind only Steelers cornerback William Gay (162 games).
Graham, a graduate of the now-defunct Turner-Carroll High School, didn't play the first three games of his rookie season in 2007 but hasn't missed a game since, extending his streak across stops in Chicago, Baltimore, Buffalo and Philadelphia.
4. The Bengals will be without Tyler Eifert and John Ross.
Andy Dalton's offense will be without two weapons Sunday against the Packers, with tight end Tyler Eifert (back) and speedy receiver John Ross (knee) both listed as out.
Dalton struggled in the first two weeks of the season, and this won't make things any easier for him. It's also the first game for Bill Lazor as offensive coordinator after Ken Zampese was fired last week.
The team hasn't scored a touchdown yet this season.
5. Aaron Hernandez had advanced CTE.
Lawyers for the former Patriots star announced a lawsuit against the team and the NFL for "hiding the true dangers of the sport" after learning that Hernandez had an advanced stage of the degenerative brain disease chronic traumatic encephalopathy, or CTE.
Hernandez was serving life without parole for murder when he killed himself in April. The CTE Center at Boston University studied Hernandez's brain after his death and diagnosed him with Stage 3 CTE, with only Stage 4 being more severe.
"We're told it was the most severe case they had ever seen for someone of Aaron's age," attorney Jose Baez told reporters.
ESPN reported that Hernandez's legal team didn't mention CTE at his murder trail because Hernandez claimed innocence.
