This Thursday is Thanksgiving, a great holiday and a terrific day for watching football. Well, usually a terrific day for watching football. This year's matchups aren't as good as some we've had in the past, but they still should offer plenty of intrigue to fantasy owners, who should be sure to set their lineups early this week. Here are the top things to watch for during Thursday's slate:

PACKERS at LIONS, 12:30 PM ET, FOX

• How will Packers WR Greg Jennings follow up his first big outing in weeks, a 5-126-1 effort Sunday? He certainly has a favorable matchup with the Lions, but he only had 6-64-0 against them earlier this season. And how huge of a game will QB Aaron Rodgers have? He ripped up Detroit for 358 yards and two TDs last month, with Donald Driver leading all WRs with 7-107-0. Also, keep an eye on the status of RB Ryan Grant, who suffered a stinger Sunday but says he'll be fine.
• The Lions had their best offensive performance of 2009 on Sunday vs. the Browns, with QB Matthew Stafford leading the way with 422 yards and five TDs. But Stafford took a monster hit late and could be forced to sit out this week. WR Calvin Johnson (7-161-1) also had his best game of the season, but how will he do if Daunte Culpepper is under center? RB Kevin Smith came through with a big-time day as well, gaining 149 yards from scrimmage and scoring, but the Packers will present a tougher challenge, as they held him in check the first time around.

RAIDERS at COWBOYS, 4:15 PM ET, CBS

• Making his first start of the season, Raiders QB Bruce Gradkowski led his team to a shocking win over the Bengals Sunday, throwing for 183 yards and two TDs in the process. But he's far from a reliable fantasy option and could struggle to top those numbers this season. The more intesting thing will be how Oakland divides carries this week, as it appears they are content to split things three ways among Michael Bush, Justin Fargas and Darren McFadden. Right now, none of them is doing enough to deserve starting consideration, but that could change in the coming weeks.
• What's going on with the Dallas offense? After looking great for a number of weeks, the Cowboys have played poorly over the past two games, with QB Tony Romo throwing for just 158 yards, one TD and one INT Sunday vs. the Redskins. Will he bounce back against a suspect Raiders defense? It will also be intriguing to watch WR Miles Austin, who's fallen flat the last two weeks after his sensational run and now will face one of the league's top CBs in Nnamdi Asomugha. One thing is for sure: Dallas should be able to run the ball like crazy in this one.

GIANTS at BRONCOS, 8:20 PM ET, NFL NETWORK

• Giants QB Eli Manning came out of the bye with a career game Sunday, torching the Falcons for 384 yards and three TDs. How will he do against a Denver pass "D" that's nowhere near as porous? And how many of his top three WRs (Steve Smith, Mario Manningham and Hakeem Nicks) will post big numbers on Thursday night? New York's backfield also has some issues, as Brandon Jacobs left Sunday's game with a knee injury. Watch his status closely this week; if he's forced to sit, Ahmad Bradshaw would have a ton of value as a featured back.
• Perhaps no team is falling faster than Denver, losers of four in a row. Who will be their starting QB in this one? Chris Simms was given a quick hook on Sunday, forcing Kyle Orton to play with an ankle injury. If the struggling Simms starts Thursday, it'd be tough to play WR Brandon Marshall. Marshall could be in for a rough outing even if Orton is under center, as the Giants boast a stellar pass defense. And can RB Knowshon Moreno overcome his fumbling issues and become a dependable fantasy back? The Broncos might be the most interesting team to watch all day.
