It’s semifinals weeks for most of us in the fantasy football world, and you start clinching up a little more when it comes to setting your lineups. Such is the case with the opening game of Week 15 as the Jacksonville Jaguars travel to play the Atlanta Falcons on Thursday night.

Falcons receivers Roddy White and Julio Jones are certainly two players many of us are counting on to get our semifinals started off the right way, but the numbers say they might not come through.

I’m going with Atlanta Falcons quarterback Matt Ryan as a confident start in Week 13 at Houston.

It’s a tough matchup. Ryan’s got injuries on his side of the ball; the Texans are tough on the defensive side of the ball. But Ryan will come through for you this week as a starting fantasy QB in 12-team leagues.

Here’s what we’re looking at with the matchup.

Julio Jones is expected to suit up against the Texans and make it into the starting lineup today after battling hamstring issues the last few weeks.

Jones missed practice on Wednesday and Thursday after missing the last two weeks of football, but should be playing today for the first time since November 13th.

The questions is, do you play him?

The short answer is yes. (The even shorter answer is y).

Atlanta Falcons wide receiver Julio Jones missed three straight days of practice this week with the injured hamstring that forced the rookie out of the Falcons’ Week 10 game against New Orleans. It was the same hamstring injury that had made Jones a questionable play leading up to the Saints game. And now his availability today against the Tennessee Titans is highly in doubt.

Career paths cross Sunday in Atlanta when Tennessee cornerback Cortland Finnegan and Falcons receiver Roddy White meet in the Georgia Dome. Finnegan’s 2011 path has him on the way up, while White’s looks like it is going down.

According to Pro Football Focus, the Titans are the seventh best team in the league in the Website’s pass coverage rankings. Finnegan, Tennessee’s top corner, is allowing 6.3 points per game to fantasy receivers in Athlon’s half-PPR scoring format.

Atlanta Falcons receiver Julio Jones jumped back on the fantasy radar after his two-touchdown, 131-yard performance in a quarter and change against Indianapolis last week.

However, he did not come out unscathed from the Colts game. He has again battled the hamstring injury this week, being limited in practice on both Thursday and Friday. He is probable for Sunday’s game against AFC South rival New Orleans.

It leaves fantasy owners wondering what to do with the rookie. Is he a reliable start?
