Injuries, unfortunately, are a pretty common occurrence in sports—especially football—and must be accounted for.
It's obviously difficult to prepare for them, but those who do never miss a beat. More often than not, they find themselves in prime position to make a Super Bowl run.
All that said, the following five WRs are seasoned veterans who have been established and accomplished NFL players for quite some time.
Let's face it—they're not young, but they could certainly help any team suffering from injuries to their receiving corps.
And who knows? Maybe they'll have that final act of revival to add to their legacy.
Check it out.
This one goes without saying, mainly because Terrell Owens is still a freak athlete and has yet to retire despite being 37 years old.
He obviously doesn't have his sick top-speed like he did when first entering the NFL with San Fran back in 1996.
However, based on the ladder drill video he did, T.O. still has the quickness and acceleration to really be a solid contributor this season.
In other words, he can still play the game.
He may have retired, but if any playoff-contending team has but one injury to their receiving corps this season, you can bet Randy Moss will be considered.
Although he became even more controversial than T.O. as their careers advanced, there's no denial that Randy Moss is an amazing athlete.
Of course, it's reasonable to suspect that a team he's previously played for won't come calling, but someone who suffers from a potential season-costing injury will.
All Moss needs to do is stretch the field like he's done his entire career, and that'll open everything else up for the offense.
Because let's be real—we're not ready for him to be completely retired just yet.
After spending all those years alongside Chad Ochocinco in Cincinnati, T.J. Houshmandzadeh slowly became irrelevant when he played in Seattle and Baltimore.
He was so much of an impact player in Cincy that it was too good to be true, so now he's a free agent hoping for at least one more chance.
The simple fact that he is a free agent makes him vastly available, and you can bet he'll be discussed when injuries to any receiving corps occur.
Although he's not a No. 1 WR, he's a solid No. 2 opposite the No. 1, and he can play in the slot if needed.
T.J.'s a little more dynamic in that regard compared to Moss or T.O., as they're both mainly deep threats.
Believe it or not, in spite of their current situation, there's an outside chance of Torry Holt returning to St. Louis.
Obviously for any team needing a stud slot receiver, Holt can get the job done, and he has the postseason experience as well to really make a significant impact.
Yes, like all these other guys he's old, but that doesn't mean he still can't play the game—it just means that his time is limited.
However, I mention the Rams because they no longer have Mardy Gilyard or Donnie Avery, and in addition Mark Clayton is on the PUP list.
Mike Sims-Walker is their best WR, and Sam Bradford could certainly use another established, reliable threat.
Not to mention the fans would love it, and Holt's return would being back the days of the original Greatest Show on Turf.
He's probably the least flashy of all the aforementioned receivers, but he's arguably the most dependable.
For 11 seasons in Atlanta (2000-2010), Brian Finneran was the latest installment of Wayne Cherbet-esque receivers.
Third down was where Finneran was most dangerous, as well as the red zone and other short/medium yard situations.
In addition, he was 6'5" and weighed 217 pounds, thus allowing him to line up outside, in the slot or even at TE if needed.
Finneran was very versatile and could also stock/run block better than most receivers because of his size and athleticism.
Any team pondering about whether they should sign him should just make the decision to do so, as he is key when it comes to crunch time.
