Description: Browns cornerback Justin Gilbert left Sunday's Week 2 game against the Saints with a head injury.
Insight: Gilbert played much better before he exited versus New Orleans after a very rough NFL debut in Pittsburgh. Buster Skrine and Robert Nelson will fill in for Gilbert, playing opposite Joe Haden.
Description: Rams defensive end Robert Quinn signed a four-year, $66.575 million contract extension according to Adam Schefter.
Insight: The deal includes $41.2 million guaranteed and keeps Quinn in St. Louis until the end of the 2019 season. Quinn was an All-Pro last year and already has 34.5 sacks in 48 career games. He is one of the best pass rushers in the NFL and is our guess to lead the league in sacks durin 2014.
Description: It appears clear the Panthers will continue to allow defensive end Greg Hardy to play while he appeals domestic violence incident.
Insight: Jury trial is expected in November, meaning unless there is a change he's going to play for the first half of the season. Hardy's 15 sacks last season were a career-high. If there had been video of the incident ... who knows?
Description: St. Louis DL Chris Long (left ankle) will need surgery and is expected to miss 8-10 weeks, according to Adam Schefter.
Insight: Long on one side and All-Pro Robert Quinn on the other side made the Rams defense a strength. This is going to knock them down a peg or two. long is probably a candidate for the short-term injured reserve.
Description: Texans linebacker Jadeveon Clowney is out 4-6 weeks after undergoing surgery to repair a torn lateral meniscus in his knee.
Insight: This loss is huge for the Texan defense, which held Washington to six points in Week 1. The defense is built on pass rush with Clowney and J.J. Watt. For fantasy, Houston's defense takes a huge hit without Clowney.
Description: Indianapolis Colts linebacker Robert Mathis suffered a torn Achilles' tendon while working out in Atlanta last week and is out for the season.
Insight: Mathis was in Atlanta working out because of his suspension for the first four games of this season for violating the substance abuse policy. The Colts looked like they missed him as they put very little pressure on Peyton Manning Sunday night. Indianapolis will have to look for a pass rush somewhere else without Mathis this season.
