There are obviously injuries every week in the brutal sport that is pro football, but it seems like Week 1 was particularly harsh for some important players. Here's a look at some of them and how it may affect things going forward on NFL odds.
Shaun Hill, QB, Rams
I honestly didn't 100 percent believe that Hill was injured in the first half of St. Louis' embarrassing 34-7 home loss to Minnesota on Sunday. Hill allegedly suffered a thigh/quad injury and was replaced in the second half by undrafted free agent Austin Davis. He had never played in a regular-season game in two previous seasons as the team's backup. Hill was seen on the sideline with his helmet on, so it seemed like he could play. Hill finished 8-for-13 for 81 yards with an interception as the Rams were blanked in the first half. As of now, the Rams are still saying that Hill is indeed hurt and that he's doubtful for Sunday's game at Tampa Bay. That game opened with Tampa at -5.5 with a scant total of 37.
Doug Martin, RB, Bucs
Speaking of the Buccaneers, we still don't know what the status of running back Doug Martin will be against St. Louis. He was in and out of the Week 1 home loss to Carolina and did nothing while in there, carrying nine times for nine yards and catching one pass for seven yards. The Bucs looked nearly as inept offensively as the Rams did in Week 1, but at least Tampa played what is acknowledged as one of the NFL's top defenses. Still, QB Josh McCown didn't resemble the guy who was terrific last season with the Bears. Losing Martin certainly wouldn't help matters.
Jadeveon Clowney, LB, Texans
Clowney's chances of winning the Defensive Rookie of the Year award likely went goodbye when he was lost for up to six weeks after tearing his meniscus in Houston's win over Washington. Clowney had surgery on Monday. He has had trouble staying on the field since joining the Texans. Clowney will be the first defensive No. 1 overall pick since 1992 to miss any games his rookie year because of an injury. I'm not sure this is a huge loss. Whitney Mercilus, a former first-round pick himself, will now start. He had seven sacks last year. Houston opened as a 3-point favorite this week at Oakland, which probably is the worst offensive team in the league west of St. Louis.
Derrick Johnson, LB, Chiefs
Kansas City's start to the 2013 season looks like even more of a fluke now. Of course the Chiefs began last year 9-0, only to lose six of their final eight games, including playoffs. I expected this team to take a huge step back this year and K.C. was rolled 26-10 at home by a very average Tennessee team on Sunday. To add insult to injury, arguably the Chiefs' best defensive player, Johnson, was lost to a season-ending injury. So was defensive tackle Mike DeVito. They were the only Chiefs’ defensive players to post positive grades in Sunday's loss, according to Pro Football Focus. Things could get ugly this week at Denver, which opened at -13.5 on NFL odds.
Cam Newton, QB, Panthers
Newton was a surprising scratch Sunday against the Bucs, which caused that line to go crazy toward Tampa Bay. The Panthers wanted to get Newton one more week to rest his fractured ribs, and things certainly worked out for the best with Derek Anderson leading the win over the Bucs in his first NFL start in four years. Newton should play this week against Detroit, which will be on a short week. The Lions handled the Giants with ease on Monday night. Carolina opened at -2.5.
Ben Tate, RB, and Jordan Cameron, TE, Browns
Did Cleveland really think that Tate was going to stay healthy this season? He never could as the No. 2 back in Houston. Tate left with a knee injury in Sunday's loss to Pittsburgh and he really wasn't missed much with both Terrance West and Isaiah Crowell -- two guys no doubt being picked up in your fantasy league as we speak -- picking up the slack. Tate's status for this week is TBA. Ditto for Cameron, who has a shoulder injury. He had two catches Sunday for 47 yards and is the clear No. 1 target for Brian Hoyer if in there. Cleveland is +6 at home against what will be a desperate Saints team.
Evan Mathis, G, Eagles
Mathis is one of the best guards in the league and a key part of what was the NFL's top rushing attack in 2013. The good news is Mathis has an MCL sprain and not a ligament tear. The Pro Bowler is going to miss multiple weeks, though. Probably at least four. Right tackle Allen Barbre, filling in for the suspended Lane Johnson (first four games), suffered a high ankle sprain and he's in doubt for this week. Philly is +3 for Monday night at Indianapolis.
Robert Mathis, LB, Colts
This might be the most significant injury on the list and Mathis didn't play Sunday. He was suspended the first four games for violating the league's drug policy but tore his Achilles' tendon while working out on his own and is done for 2014. Mathis led the NFL with 19.5 sacks a year ago and the Colts really have no one else close to him from a pass-rushing perspective. They barely touched Peyton Manning in Sunday night's loss without Mathis in there (he sacked Manning twice last year in a win). Indy is going to have to win a lot of shootouts now. The Colts' total of 53.5 for Monday's game vs. Philly is the highest on the board.
