A brutal opening loss for the Chicago Bears against the Buffalo Bills also included some injuries to key players.

Wide receivers Brandon Marshall and Alshon Jeffery (they're kind of a big deal) left the game with leg injuries, though Marshall tried to play through his and came up lame trying to catch a pass on what would've likely been a big play in space (summarized how things went on this day). There don't seem to be concerns that Marshall's injury is serious, though.

And as for Jeffery, reports from the Bears' sideline kept saying he was probable to return to the game after a hamstring injury, but never did. It seems like the Bears were just being extra cautious on their star third-year receiver.

While Marshall and Jeffery were each out with injuries on Sunday, the Bears were down to Santonio Holmes, Josh Morgan, and Micheal Spurlock at wide receiver. If you follow me on Twitter, you know that I've made it clear that I don't think Spurlock should be on the team and I don't understand what he showed during the preseason/camp to earn a precious 53-man roster spot. The Bears talked about Spurlock's return abilities and obviously have been full of question marks there, but he muffed two punts in the preseason, without even having a single good return to top it off. And at wide receiver, he showed very little. It just seemed like there were a few players more deserving of a roster spot than Spurlock out of camp.

Well, on Tuesday, the Bears finally released Spurlock (after he had a bad drop on Sunday... after Cutler for some reason threw to him), and re-signed veteran offensive lineman Eben Britton:

The Britton move was about the most predictable move ever, as two other players that suffered injury on Sunday for the Bears were starters on the offensive line: left guard Matt Slauson and center Roberto Garza. Reports are that Slauson and Garza suffered the dreaded high-ankle sprain, an injury that frequently takes 4-6 weeks to heal.

Britton is a veteran known for his versatility on the offensive line and probably would've made the team if not dealing with an injury himself during the preseason. The Bears even lined up Britton as a "tight end" at times last year as an extra blocker.

Brian de la Puente will be the starting center with Garza out, and many would like for de la Puente to keep the job even when Garza is healthy. Here's what Pro Football Focus said about de la Puente, whom they gave their second-highest grade on the Bears for Sunday's game (the grade has since been increased to +3.7):

Brian De La Puente, C: +3.2 

Breakdown: Playing 45 snaps in relief of the injured Garza, De La Puente was integral in the Bears’ comeback attempt. Routinely exhibiting strong work in the run game, he helped open the door for Matt Forte’s solid day. This shouldn’t come as much of a surprise, though, as De La Puente put up a combined +40.8 grade in three years starting for New Orleans. How he ended up in a back-up role is mind-boggling, and if he continues playing as he did yesterday, he shouldn’t stay a backup for long. 

Signature Stat: Perfect in 33 snaps of pass protection.

And guess which Bears player had PFF's highest grade vs the Bills (and PFF's highest grade for any guard in the NFL through week one, actually, at +4.8))? None other than the guy that replaced Slauson at left guard, Michael Ola.

So, there's reason to believe the Bears will be fine on the starting offensive line while Slauson and Garza are out, but their depth obviously took a hit, and that's where Britton comes in. Provided Britton is healthy, quite a fortunate situation to be able to bring back a guy off the street that was solid and very versatile for them in 2013.

In another move on Tuesday, the Bears signed Greg Herd (was with the Bears for a part of preseason) to the practice squad and released defensive tackle Roy Philon from the practice squad:
