One of the most integral parts of fantasy football is knowing how to play the injury reports, and Week 2 will leave you with plenty of decisions to make.
You have to know when to keep that certain questionable running back on the bench and when to roll the dice with your star wideout who has been dealing with hamstring problems for what seems like his entire life.
It's not easy, but luckily, we're here to update you with all the latest injury information as it becomes available.
Greg Jennings, WR (Green Bay Packers)
UPDATE: According to ESPN's Rachel Nichols, Greg Jennings is officially inactive for Thursday night's game.
The veteran wide receiver didn't practice on Wednesday (via ProFootballTalk's Evan Silva) and is listed as doubtful for Thursday night's matchup with the Chicago Bears. Even though he isn't expected to play, Jennings has to be officially ruled out.
Jeremy Maclin, WR (Philadelphia Eagles)
According to Jeff McLane of Philly.com, Jeremy Maclin missed yet another practice on Thursday and has yet to see the field this week because of a hip pointer. However, Andy Reid still expects him (and DeSean Jackson) to play Sunday (via CSN Philly's Reuben Frank).
Jonathan Stewart, RB (Carolina Panthers)
Jonathan Stewart once again was listed as a full participant during Thursday's practice, and it appears that he will be ready to return from his ankle injury on Sunday.
The Panthers' run game never got started in Week 1 and could seriously use Stewart's help. Expect him to get thrown right back into the fire.
Pierre Garcon, WR (Washington Redskins)
Pierre Garcon was "very limited" in practice on Thursday, according to head coach Mike Shanahan (via Tarik El-Bashir of CSNWashington.com). It doesn't sound as though Garcon will see much action, if any, on Sunday against the St. Louis Rams.
Ryan Mathews, RB (San Diego Chargers)
According to San Diego Union-Tribune beat writer Michael Gehlken, Ryan Mathews participated in full pads on Thursday, marking the first he's done so since he broke his collarbone more than a month ago. Week 2 has always been Mathews' target return date, but it's still a large unknown whether or not he'll be out there on Sunday.
