Depth is getting more and more important in fantasy football leagues this year. The latest argument to dig deep on the waiver wire involves a slew of stud wide receivers nursing injuries heading into Week 4.

Here's the latest on a few star wideouts:

Eric Decker, Jets

The wide receiver — who often plays second fiddle to Brandon Marshall —is questionable with a shoulder injury heading into Sunday's game against the Seahawks. He's had a few spectacular games for New York this season but could be stuck with a clipboard in Week 4.

"It's a concern. Hopefully it's not (serious)," Jets coach Todd Bowles said Thursday.

Decker did not practice Thursday which is a bad sign. Rookie wideout Jalin Marshall also did not practice. If you have Quincy Enunwa on your roster put him on standby for this week.

Dez Bryant, Cowboys

Reports have been all over ESPN this afternoon but in case you missed it, the Cowboys star pass-catcher has a hairline fracture in his knee and is out Sunday, and could miss three weeks. Bryant failed to show up Monday for treatment and Tuesday at team meetings, so the diagnosis comes two days later than usual.

Luckily for Dallas fans, the team is playing a 49ers team it can handle without Bryant. Look for the Cowboys to rely on their elite offensive line and running game as Bryant heals.

Sammy Watkins, Bills

Buffalo's speedy receiver did not practice Thursday and his status for the team's Week 4 game will likely be made before gametime. He has a foot injury that many are calling a pain tolerance issue. 

NFL Network's Alex Gelhar says: "Doesn't sound like Sammy Watkins is practicing again today. Even if he plays, I think you have to sit him."

Mohamed Sanu, Falcons

The Atlanta receiver was injured in Monday night's win against New Orleans and hasn't practiced as a precaution. He's the Falcons WR2 and will likely be a gametime decision Sunday.

DeSean Jackson, Redskins

The oft-injured speedster Jackson did not practice Thursday — again as a precaution. He is more likely than not to suit up in Week 4 but beware of a pregame decision to sit him.
