So it's the eve of the season opener, and your roster needs some bandages. Maybe you got burned by the auto-pick or bitten by the injury bug, or maybe you just had a plain, ol' bad draft. It happens.

Now you have some holes to fill and you're scrambling to make a last-minute pickup to salvage your roster for Week 1. Here's a position-by-position breakdown of potential free agents who might be able to help, but we're not making any promises you'll find a needle in that haystack.

QUARTERBACK

Yeah, right. Better make a trade.

RUNNING BACK

See "Quarterback."

A few of the less desirable "handcuff" guys are probably out there, such as Tennessee's Javon Ringer, Philadelphia's Leonard Weaver, Tampa Bay's Earnest Graham and Cleveland's Peyton Hillis, all of whom are one break away from having fairly significant value, but any backs available on the free agent market at this point probably need an injury to someone in front of them to gain any fantasy swagger.

WIDE RECEIVERS

Finally, a position with enough depth to facilitate a free agent find at the 11th hour. Not many of these guys are viable Week 1 starters, but a few of them can add depth now and might just blossom into more than bye week bandages down the road. (Percent owned as of 5 p.m. Wednesday)

• Chris Chambers, WR, Chiefs (34% owned in Yahoo leagues, 9.9% owned in ESPN leagues) -- Chambers is virtually a co-No. 1 receiver along with Dwayne Bowe for a team that is likely to play from behind quite a bit, and therefore ought to be throwing plenty. He had 60 yards or more receiving in five of nine games after joining the Chiefs last year.

• Mike Thomas, WR, Jaguars (5% Yahoo, 3.3% ESPN) -- Might Thomas be this year's version of teammate Mike Sims-Walker? He might. He's quick and has great hands, and with 13 catches over the last two games of 2009, he could be especially valuable in PPR leagues.

• Nate Washington, WR, Titans (19% Yahoo, 2.0% ESPN) -- While folks were drafting teammate Kenny Britt, Washington was quietly claiming the starting job - and thus the fantasy value - assumed to be Britt's. If he can improve on last year's 47 catches for 569 yards and six TDs, he'll be a steal as a free agent pick-up, especially in PPR leagues.

• Josh Morgan, WR, 49ers (5% Yahoo, 8.8% ESPN) -- Morgan was a popular sleeper pick who turned out to be a bust a year ago, but he might just be a year late in blooming. With Michael Crabtree working opposite him, he should be able to get open, and if Alex Smith continues to develop into a legit quarterback, Morgan will have some value.

• Danny Amendola, WR, Rams (11% Yahoo, 1.6% ESPN) -- Laurent Robinson shot up the draft boards when Donnie Avery was lost for the year, but Amendola has been largely overlooked. When Mark Clayton gets up to speed in the offense, Amendola is likely to move back to the slot, where he had a fair amount of success last season.

TIGHT ENDS

Like running backs, all the guys who are really worth having are probably gone. But tight end can be a feast-or-famine position, and if you're willing to endure a big, fat zero some weeks, you might end up with a big payoff the week your guys hauls in a couple short touchdown passes. If you're in a pinch, grab one of these guys, but the better move might be to hold out until folks start to drop those second and third tight ends they drafted as they scramble to cover bye weeks at other positions.

• Marcedes Lewis, TE, Jaguars (27% Yahoo, 3.1% ESPN) -- Lewis gets a bad rap because he has never lived up to his potential, but he's still the starter in a decent offense and has a good rapport with quarterback David Garrard. You could do worse.

• Bo Scaife, TE, Titans (4% Yahoo, 1.7% ESPN) -- If you've been playing fantasy football for a while, chances are good you've owned Scaife, and you've been disappointed with Scaife. But the guy has caught at least 45 passes each of the past three seasons, and if he just gets some more red-zone looks, he could be quite an asset.

• Rob Gronkowski, TE, Patriots (9% Yahoo, 9.4% ESPN) -- You'll have to be desperate to go this route, because Gronkowski is still listed behind veteran Alge Crumpler on the depth chart, but he seems to have edged himself into position for more playing time and caught four touchdown passes in the preseason, and the Patriots no longer have Mike Vrabel poaching red-zone targets.

Hope you find at least one hidden gem in there to bolster your roster. That's all I have for now, but check back tomorrow for the Gameday4Cast, and we'll break down the matchups and help you get your lineup set for opening night.
